Crayon Physics
The YouTube game is called Crayon Physics Deluxe and this is just a quick and ugly prototype of that game. You can’t draw anything else than squares in this game.
Sorry for the hostility, but subtle tactics didn’t seem to work.
Here’s my tenth done-in-under-a-week game. I would have liked to spend few more days with the game, but unfortunately I didn’t have the time. As usual the game is open to critique.

Instructions
You play with crayons and physics. The goal of the game is to move the red ball so that it collects the stars. You can cause the red ball to move by drawing physical objects.
With left mouse button you can draw and with right you can remove objects.
Space - Will reset the level.
Esc - Will open the menu.
Alt + enter - Will toggle fullscreen.
Alt + F4 - Will quit the game.

[…] Crayon Physics is this month’s Kloonigames experiment. I’m usually terrible at these kinds of physics/puzzle combinations, but that didn’t stop me from having a lot of fun. The goal is simple, direct the ball to collect the stars. Draw boxes that will fall due to gravity, interacting with the other objects on the screen, such as bumping the ball to start the whole process. Very fun, with a few very clever levels. Petri would have liked more time, and I agree. Some more levels, perhaps an editor, and this would be about perfect. […]
June 1st, 2007 at 9:17 pm
Awesome stuff. A bit frustrating at times but pretty good. I’m not very much into physics so I can’t help you much there. I can say that at least for the most part I appreciated the atmosphere of the game and had fun.
June 1st, 2007 at 10:26 pm
@KKairos: Glad to hear that you enjoyed the game. Some of the levels are difficult on purpose. I added the ability to load any level in the game to compensate this. So if you can’t complete a level, feel free to test the others.
June 1st, 2007 at 11:12 pm
Wow, this one is the most enjoyable game of yours, and plus to this, this is, technically speaking, the best game of yours too. Good utilisation and application of physics along with a cool music and a nice and fluent gameplay. I’ve found no bugs, so this means engine (or coding skill?) is improving also!
Very neat and perfect!
June 2nd, 2007 at 12:06 am
I like the concept and 90% of the execution, but I’m a little confused as to why some objects I draw stay exactly as drawn while others automatically become rectangles.

@Decipher: Wow, thanks a lot for the feedback. Yeah, the technically it was a bit of challenge to create, but I have to tell you that I really enjoyed the challenge. I should probably do more technically challenging stuff. I don’t know if my coding skills are improving (I think they have decreased by all this prototyping), but I changed the physics engine.
@Erik: I’m glad you enjoyed the execution. The reason why some objects are converted into rectangles and other stay like they are is an technical one. I wanted the objects to the stay the way they were drawn, but this posed some problems. If you draw a L -shape the object would behave like an box, but the shape would be completely different. So the solution was to convert the shapes that don’t correspond a box enough to a “perfect” box.
June 2nd, 2007 at 3:13 am
This is really impressive! One of the best minigames I’ve ever played. Really nice design and good choice of music. I wish I had something constructive to say, but I’m way out of my league here. I’ll be keeping this on my harddrive.
June 2nd, 2007 at 3:16 am
I love all your games but this one is particularly wonderful. Great great work.
June 2nd, 2007 at 7:32 am
Wow, it’s really just totally awesome and beautiful, very nice work!
Two super totally minor comments:
1. The aesthetics are just perfect, except I wish the star wasn’t stretching since that says “sprite” instead of “crayon drawing”. I was thinking maybe it should just be redrawing itself with a yellow crayon as its animation instead of stretching…that way it’d fit the theme better, but still be actively drawing attention to itself.
2. I didn’t realize you could draw a single line at first, and I think it was slightly incrementally more fun that way, trying to draw thin boxes with the mouse. It added a little bit of a really subtle dexterity action component to the puzzles on some of the levels, trying to hurry but still draw a thin box. Not too much to be frustrating, but enough that it’s interesting, and it makes long thin boxes more difficult to make, which is a kinda cool feedback loop since they’re “more powerful” in some sense.
But, again, it’s just really marvelously delightful! Thanks a ton for making it!

Congrats, this reaches a milestone in your efforts and definitely shames Pluto into number 2 (so I probably won’t have to execute half of your development team).
There has always been a visceral feel to your games, on account of the physics engine being the control method, and Crayon Physics goes further than that in creating a whole world of possibilities you can explore. I’ve sent you an email to showcase just user content creation.
The best advice I can give you: Create a level editor. The lack of levels is a triviality when the players can create their own content. You ‘re going to get press for this game, so don’t miss the opportunity to expand your fan base. And you know if you don’t do it now, you aren’t coming back to it (much like the now legendary high score table for pluto, hehe)
June 2nd, 2007 at 1:01 pm
Thanks everybody for your comments.
@cactus: Thanks for the feedback. Don’t sweat it, no constructivism required on the comments. I enjoy the “Great work, man” -comments as much as I enjoy the constructive criticism.
@Rod Humble: Thanks for letting me know, what you think of the game. Always a pleasure to hear from you.
@Chris Hecker: Wow, thanks a lot for taking the time to play the game and for writing the comments.
1. You’re right about the stretching star, being a bit off place. I originally intended to make it a redrawable star, but I went for the stretching because it was easier to do
Now that you mentioned the fact that it doesn’t quite fit in the game, I kinda feel bad for my laziness. I’ll put this one on the list of things to fix, if I ever create a new version of the game.
2. That’s an interesting point. It’s true that the thin boxes are “more powerful” and that’s why drawing them should be more difficult. But I added the line drawing because I thought the drawing of thin boxes can be really frustrating if you don’t have a very stable mouse hand. And I wanted to make the drawing of objects as easy as possible (because it’s the interface, not the game), so that the puzzles weren’t about drawing, but about the physics.
But, again, thanks for the thoughts provoking comments.
@bigbossSNK: Thanks for the feedback. I got that e-mail of your’s. I agree with you that the game really needs a level editor. And if I have the time I’ll try to create one. We actually discussed this with Bill on the2bears.com. Btw. The pluto’s hiscore tables are coming, someday
June 2nd, 2007 at 1:24 pm
One of your best games in my opinion. I love the experimental gameplay, the music, aesthetics, everything in it just fits the theme so well. A great one for your tenth game, and I agree with the above comments. All it needs is a few more levels, or maybe an unlockable playing mode.
Come to think of it, Crayon Physics reminds me a bit of Chalk by Joakim Sandberg. So many good indie games released nowadays.
June 2nd, 2007 at 1:53 pm
@Keidas: Thanks. It’s nice to hear that this is one of my best games, since the last one (Daydreaming in the Oval Office) was one of worst ones
I’m glad to hear that the theme worked, because it’s a very different kind of theme for me.
I bumped into Chalk while I was working on the game. I think Joakim did a really great job on the drawing gameplay there, I was really impressed with the simplicity and fun of it. It’s a funny coincidence that we both released our games so near to each other.
June 2nd, 2007 at 2:18 pm
…Also, I think I’ve noticed a small bug in the Load Level menu. It sometimes lets you play the next level, even if you haven’t unlocked it yet. This happened after I resetted the level I was stuck in, but I couldn’t replicate the bug, so it’s propably nothing bad. Just thought to inform you anyway.
June 2nd, 2007 at 3:30 pm
Great game! It would be really worth to spend more time on it someday in the future…
June 2nd, 2007 at 5:37 pm
Wow! Great&very enjoyable small piece of art
A sorry that only comes with 7 levels -I won’t say nothing ’bout a level editor because is going discussed- but except this… :))))
Thanks for share with us
June 2nd, 2007 at 5:59 pm
@Keidas: It’s not a bug it’s a feature
I decided to put the load menu there, to help people who get stuck in some level, so that they can try out the other levels as well. So you can load any level at any time.
@Starky: Thanks, I’ll try to find some time to make some improvements to the game.
@Oblo: Thanks for the complements. There are a lot of people voting on for the level editor. I think I really have to create one.
June 2nd, 2007 at 10:54 pm
This is a great game ….. wish there was more levels.
Maybe you can explore the free form shapes more for problem solving.
The music is really well suited for the cerebral work.
Thanks
June 3rd, 2007 at 2:08 am
@smelly: Thanks for your comments. If I get the level editor done, then there probably will be few new levels. But until then I can’t promise anything.
The free form shapes would be interesting, but they are a bit of a challenge to create from the technical stand point.
June 3rd, 2007 at 3:08 am
One more thing I was reminded of when discussing the game with some friends that I figured I’d post:
I used “bugs” in the physics to solve a bunch of the puzzles, meaning I drew overlapping boxes and let the solver push them apart to create shapes and movement that I wouldn’t have been able to build by just letting things drop. I found this enjoyable, but if it wasn’t one of your design goals you might put some thought into that. At least one person I talked to got frustrated with the game and I think it’s because they tried to play it “right” rather than making a big mess of things. : )
Chris
June 3rd, 2007 at 7:35 am
[…] fous la gravité dans ce bordel, et on va voir comment que tu te démerdes haha”. Eh bien, Crayon Physics est de cette veine […]
June 3rd, 2007 at 12:16 pm
@Chris: Thanks again for taking the time to write the constructive critique. It’s too rarely I get such treats
Originally I intend the puzzles to be solved without drawing overlapping boxes (by this I mean that you couldn’t even draw a thin line under the ball). But while I was designing the puzzles I figured that there wasn’t much you could do this way. The ability to draw something underneath the ball really open up a lot of possibilities for the puzzles. Actually the levels (1-3) are solvable without drawing anything underneath the ball, but they are much easier if you figure out that you can draw a thin box under the ball. To solve the level 4 (that’s the level were there are the small platforms on opposite sides of the level) you have to draw a bridge underneath the ball (or there might be way to do it, without drawing the bridge) and I think this is the reason why some people have been stuck in the level 4.
So to some extent I intended the puzzles to be solved by using the “bugs” in the physics. But I didn’t intend the players to draw big mess and explode things up, but then on the other hand I didn’t want to restrict the players from playing around anyway they wanted.
But thanks again for the comments, I really appreciated it.

Petri,
I think it’s your best. Apparently, your prototyping training is starting to give you more room in your head to come up with much better stuff.
You tackled the game’s “infant play” evocation from graphical, musical and interaction aspects. The objects being a ball and a star helps this too.
It’s maybe too hard :).
Great Work!
June 4th, 2007 at 3:48 am
The most fun I’ve had in a while in a mini-game.
Please oh PLEASE get this in flash so I can use my wii-remote to play this game!
June 4th, 2007 at 7:36 am
@Daniel: Thanks a lot for the feedback. This one was a bit of a technical challenge to make, but I’m happy that it turned as well as it did.
I was a little afraid that the theme of the game would turn out to be too childish, too over the top cute. But I’m glad it didn’t. A lot of it got to do with the music, I was lucky to find such an great piece of music by _ghost.
@Stephen: Thanks. I’m sorry but I don’t think I’ll be able to make a Flash port of the game. My Flash -skills are almost zero and the graphical style is something that’s pretty hard to do in Flash.
June 4th, 2007 at 11:59 am
The game is amazing, good work Petri
That was my dream to play a physics game where I can draw stuff myself and watch it interact. Put some more work to it and it will be a miracle 
June 4th, 2007 at 6:22 pm
@Darooo: Yeah, I too kinda always wanted to see a drawing come to life and I’m glad I got it working as well as this one. I’ll try to squeeze some more time into it and I hope it turns out even better.

This is greatness. I love the idea and the music. I couldn’t stop playing until I beat it.
June 5th, 2007 at 7:56 am
Happy to know you liked the game. Sorry that it was so short.
June 5th, 2007 at 6:54 pm
hey, I just took a look at your data. Ya know….
A level editor (or level editing GUI) would REALLY open this game up. Since it’s all XML files there just needs to be something for people to visually see how the levels look.
June 5th, 2007 at 7:50 pm
@Stephen: Yeah you’re right.
Because the level data is pretty straight forward it’s possible to crank out a separate program that does the level editing. But I’m tempted to create in the game an in-game editor, that’s simple enough for people to use, but allows the users to create pretty complicated levels.
When I worked with the game I created a pretty horrible level editor for myself. It would be a pretty simple operation to make it a little bit more usable, but still it would be quite horrible level editor. If I can’t find the time to create a proper editor, I’ll release that one, so technically savvy people can create some levels.
June 6th, 2007 at 10:02 pm
Whoops! Let me post in the game-specific page this time, instead of the general criticism page.
Some ideas for differentiating fixed elements:
* a distinct color, especially black
* metallic colors
* ink, especially print; this suggests the player is drawing with crayons on a scrap of paper rummaged from somewhere else, maybe a printer error tossed in the trash, although I’d miss the current background of cheap paper like I got in grade school
* solid shading (even better if you can shade outside the lines a bit)
Concerning a better engine for custom shapes: I particularly missed triangles. Ramps would be handy, and I often wanted to drop a wedge point-down to roll the ball away from a large block. Custom shapes offer more tactical variety, but predictability is more important. If custom shapes won’t work properly, I’d be comfortable with something that drew a precise rectangle every time, with edges at the bounding x,y values for all points drawn.
June 7th, 2007 at 5:00 am
Something you may not of intended (that made it a LOT easier in the two star level): if your ball falls off the screen a few seconds later it re-appears. So for the two-star level I launched at the start on the left, fell off the screen, re-appeared & fell off the starting platform to the right to get the last star.
June 7th, 2007 at 5:19 am
Just wanted to point out that in the teeter totter level, I’m having A BLAST launching my ball in to orbit.
June 7th, 2007 at 8:36 am
@mdlake: Thanks again for the feedback and suggestions. I liked the ink idea, that the fixed elements would be drawn in ink and the paper would look like a true scrap paper. That’s a nice idea.
I’ll try to get the custom shapes working. They would help even with the triangles and rectangles. Because a lot of the times the drawn rectangles aren’t exactly straight, they are a bit tilted, and the engine has to straight them out in order for them to work. Custom shapes could fix that also.
@Stephen Howe: Yeah, I intended the star collecting to work that way. The reasoning was that it’s up to the player how he wants to play the game. The stars can be collected without dropping the ball, but if you can’t make it you can go for the easier solution.
It’s the same reasoning why I didn’t include any kind of restrictions on the drawing. I thought of adding stuff like “you can only draw this many shapes in this level” -kinda stuff, but I decided that it would only be irritating and take away a lot of the fun.
June 7th, 2007 at 12:27 pm
Hey, if you write this using libsdl, libpng and zlib, why don’t you port it to linux? I would really like to play this game but I don’t have MSVCP60.dll in my wine.
June 7th, 2007 at 2:34 pm
Honestly, this is simply one of the best and most original games I’ve played in years! I love absolutely everything about it: the mechanics, the graphics, the music (I thought the theme song from Pluto strikes back was insuperable, but you’ve surely proven me wrong :D)
Thanks a lot for making a brilliant game like this!
There is only one thing this game needs: more levels! Or at least a level editor. I surely hope you’ll make a new release soon, because I’m absolutely hooked!
June 7th, 2007 at 2:40 pm
This is an amazing game but I got to the end in 30 minutes. I wish you would make some extra levels, because this might be your best game
I hope that since you have done all that physical stuff and game engine, it won’t be too hard to add levels.
June 7th, 2007 at 5:49 pm
Neat idea.It has a great look to it. Looking at some pictures of others using the game I can’t believe I did not try a seesaw!
June 8th, 2007 at 12:21 am
@Pta: I’ve had couple of guys trying to port my games to linux, but they haven’t had any luck. Basically there are some issues with C++ templates that should be resolved. Currently I’m not using linux as an operating system myself, so I can’t fix the issues. Maybe if I fix the game so that it compiles under MinGW… I’ll probably fix the problems sometime in the future, when I have the time do it, but I wouldn’t count on it happening any time soon.
@Venca: Wow, thanks a lot for the kind words. I found the background music by pure luck, so I’m glad it works as well as it does. I’ll try to do the new version with level editor as soon as possible.
@Kael: The adding of new levels isn’t a big issue. It’s the making of them that takes some time
I’ll try to crank out the level editor so other people can also create levels for the game. And possible when I release the level editor I’ll release a new version of the game with new levels.
@BenS: Thanks. Yeah, some people came up with pretty creative solutions to the levels.
June 8th, 2007 at 9:09 pm
Yeah, I meant the making:) Anyway, great game, it’s worth extending.
June 8th, 2007 at 10:17 pm
Maybe you should release the level editor you used to make the game. Also, instead of making another one, just improve the current one.

@Paul: Thanks for volunteering. I’ll send you an email about the subject. I want to release my games and my game engine as open source, but it still needs a lot of tidying up to do before that and also it requires a huge amouth of documentation. My time is pretty restricted when it comes to that.

Hi,
This game is really, really, really, excellent.
Thanks a lot for making it !
Is there an way to create new maps ?
I’m sure a lot of people (including me) would be glad to do new some new maps…

However, I’m afraid I can’t give any constructive criticism without an OS X version!

June 15th, 2007 at 12:54 am
@Etienne: No problem, I really enjoyed working on the game. I’ll try to release the level editor so other people can also release some new levels for the game. I don’t own a Wiimote so I can’t really test the game with it, but I’m not really sure if the game would be any better with a Wiimote. A tablet PC would make amazing, but I can’t afford one
@Otávio: Yeah, you can make new levels just by editing the XML files. Or you can almost make new levels, you also need to do the graphics.
@eobet: Sorry for the lack OS X version. But in the mean while you can check this gameplay video on video.google.com.
June 15th, 2007 at 1:25 am
My word, this is a simply stunning project, thank you so much for working on this ! The combination of the beautiful childish aesthetic quality and the ever so charming audio loop just kept me entirely enthralled throughout the ‘demo’. I hope to see this project grow and grow as it really has made my evening playing through the levels. If you ever need any more music then feel free to use some of mine (see website: tracks 11,13 & 15 remind me of the atmosphere I felt whilst playing the game ) but yeah, thank you once again for this great little game. This will stay on my hard disk for a long long time (until you release the next version that is
)

@petri.purho: I did a new level
It’s the level_09.zip file in my public Box http://public.box.net/otavio
June 15th, 2007 at 2:30 pm
@Pete: Thanks a lot for the kind words and encouragement. I’ll try to make sure that the project continues to grow.
I listened the tracks you recommended and played through Otávio’s new level and they fit perfectly. The tracks were wonderfully ethereal and soothing. Very atmospheric. A bit more darker than the current soundtrack of the game, but just beautiful. I just downloaded the whole album and I’ll listen through it tonight.
I’m always looking for music that I can use in my games so big thanks for offering your songs to my use. I never know for sure what kind of game I end up creating, so I can’t promise that I’ll find use for your music, but I’ll let you know if I end up creating a game were your music fits.
@Otávio: WOW, thanks a lot for creating the level. It was great, I really enjoyed it. I have to admire the fact that you managed to create the level with only using XML. It must have been pretty difficult task to accomplish. How did you actually do it? I’ll probably post this to the blog during the weekend.
June 15th, 2007 at 8:06 pm
Hi petri.purho, actually I studied the XML file, looking for physics references and the coordinate system. The rest was easy.
Today I’ll create an simple editor in SDL because I loved the game!!
Your game is amazing!! And the “modularity” in XML files was a brilliant idea.
June 15th, 2007 at 11:50 pm
Another vote for a Linux version here.
I read your response to the other person but I’m just letting you know there are quite a few of us penguin fanatics wanting to try out the game.
Someone might be able to get this working under Linux (or Mac or another OS) if you released the source. Since you aren’t making a profit from this or anything it’s just something you might consider some time in the future.
June 16th, 2007 at 1:53 am
This was absolutely fantastic, as many before me have said.
I do hope that you pursue this project further, I must admit… I was quite disappointed when it ended. Although, for 5 days work it’s excellent.
This is just such a nice game… It’s difficult to explain. It’s just so, childlike which is what makes it so fun! Simple, fun, well made and a nice challenge… what more do you want?
Kudos to you. I really really really hope to see more puzzles =)

Only problem is I’d like to do it with properly: Tidy up the code, write a little bit of documentation, perhaps some tutorials… And all that takes a lot of time, and unfortunately I’m way too busy at this moment. I’ll probably to do it some time in the future.
@Kieran Duncan: Thanks for the kind words. I’ll try to make sure that Crayon Physics continues to evolve.
@Schwallo: You can try the Otávio’s level.
@Jhon: Thanks. Apparently there are quite a lot of people who discovered my site through http://www.zanorg.com. I just looked at my stats and there’s a spike in traffic coming from http://www.zanorg.com.
@mica: Thanks for the feedback. I’ll try to release some new levels to the game or at least get the level editor out.

Great game! I would love to see more levels! Anyway try with a pen tablet and you get double fun. I use the new Wacom Bamboo. If you want, check at http://www.wacom-europe.com/bamboo/?lang=en.
June 18th, 2007 at 6:34 pm
Thanks everybody for the feedback.
@mody: I really should steal a wacom from a friend, just to test the game. Jean T mentioned that he played the game with tablet PC.
June 18th, 2007 at 8:29 pm
I discovered this game just a week ago. Thank you so much, it was really addicting! I showed it to some friends yesterday and they enjoyed it too! We altogether agreed that a level editor would make it perfect, so that I tried to create my own levels, following Otàvio’s instructions.
Well, It’s not really the same graphic atmosphere but I tried to set up a videogame theme (Super Mario Bros3). Maybe it was not what you would have expected(regarding the graphism). You can test my second attempt here :
http://public.box.net/tahina795269
(yeah, I really followed Otàvio’s instructions). I also tried to change some settings, such as the ball and the music(in which I succeded), or the star (I failed to make it turn around). Maybe I was too ambitious, but it would be great if you told us how to change this kind of settings (and also the level selection menu).
Once again, thank you so much!
(Please forgive my mistakes in English)
June 18th, 2007 at 8:52 pm
@logr: Wow! Thanks a lot that was a really kinky little puzzle. Took me a while to figure out how to solve it. I think I spend almost 20 minutes with that one
Great theme, I really liked it.
If there’s more interest in this kind of modding, I’ll write a post that describes the XML file format and other stuff.
Thanks again for the trouble you took.
June 18th, 2007 at 11:27 pm
Thank you! I feel so relieved. I thought it would not be that good a level. I’m really glad you enjoyed it!
Yeah it took me some time just to change the ball(I tried with Paint but there was no transparency, so I had to download Gimp and understand how it works). I even thought of replacing the star by some stuff from Mario (like a 3D star or even Princess Peach), but it seemed a bit like an extra.
So I focused on the xml code then choose what kind of level I would create(I have thought of a flipper, an horizontal level, even an “advanced tutorial” to show people some tricks which can be useful, but I thought it would be some kind of a spoiler).
Another difficulty I ran into was to assess the difficulty and the solution in the meanwhile : if I put this here, how can I overcome it, etc.
The next thing to do was to input the coordinates (it took me most of my time). Then I tried to solve it. I succeeded by using some tricks, but then I found another way while my brother was trying it. I may consider it another trick, but basically, it uses some parts of your levels.
I thought I would create other levels this week. So bad I still have my entrance exams for a fortnight! By then I hope I’ll have new ideas (the Mario parts made me think of a platform game instead of a puzzle. Maybe it’s just me…)

Thank you. I’m still having trouble with my schedule. I’ve yet managed to create a new Nintendo level which you can test( http://public.box.net/tahina795269 ). Actually I couldn’t stop until I have completed it.
I think this is really a tricky one. I tried to solve it without any tricks but I couldn’t. Maybe I should try something simpler next time.
I wanted to change the star into what’s above it but I thought it would be too time-consuming. I already have something in my mind regarding my next level. I’ll try to make it simpler but I’ll keep on setting a Nintendo theme. Just wait and see!
(I have also found it difficult to close the right border using the xml, but I succeeded in making my level a “one shot”. I had to press the spacebar countless times:) Now it’s your turn!

I just edited the level pack so that it also includes your newest level.
It was a difficult one, but I managed to solve it. Editing the friction was a nice trick. It made some of techniques impossible to use.

June 20th, 2007 at 9:26 pm
I dunno if anyone has mentioned this in the past. But Crayon Physics works perfectly on Linux under Wine. You just need to download a missing dll from: http://www.dll-files.com/dllindex/dll-files.shtml?msvcp60 then extract and copy it into the crayon directory.
Mine works fine, but without sound though that’s probably my fault. Great game!

@biri: Thanks.

A beautiful game, I had a lot of fun with it. I hope you make a sequel =)
It really flexed my brain, the second stage actually stumped me quite a bit. It took a couple of minutes for me to “free” myself and think in terms of the game, not by other stuff I’ve played. Kudos (great choice for music too).

petri.purho : the “book” is readable online (http://www.catb.org/~esr/writings/cathedral-bazaar/cathedral-bazaar/ ) (and is very short), I posted the wikipedia url since it might provide a sort of summary. It was to suggest you to really let others help you with tidying and everything

June 22nd, 2007 at 1:14 am
Hey, I just want to let you know that after hearing about this breifly on GFW Radio, I liked the concept and checked it out. I am now addicted and trying to think of new ways to play the levels. For example, on the Spinners Level, my original concept was to just make one long box bridging all of the spinners and going across. I now am trying to use the spinners to shoot the ball from one end to the other. I was suprised how much you can do with See-Saws and this thing:

http://blog.thedamocles.org/index.php/post/2007/06/24/Putain-y-en-a-qui-sont-doue
(in french)
Are you still considering releasing the source code under an open source licence ? It would be a evry good news as this game has a real potential !!
June 26th, 2007 at 4:31 pm
Jesus, this game is brilliant. It’s so… meditative. The game provides you with a goal and nearly omnipotent powers with which you can achieve it. No level has a “right” answer; experimentation is always rewarded. You’re free to devise different solutions depending on how you’re feeling at the time. Many puzzles can be solved with nothing more than a nice straight line, but if you’re in a whimsical mood, you can come up with all sorts of inefficient but oh-so-freaking-satisfying Rube-Goldbergian solutions employing see-saws and counterweights.
I would pay for this game. If there’s a commercial version available, with a full-featured level editor, I will pay for this game.

This game amazed me. Such a simple premise, yet so very complex and open-ended in the solutions. I absolutely would buy this game if it was a full game, with a lot more levels and maybe the ability to draw some other shapes, like circles or triangles. Overall, this is a very, very great game.
June 28th, 2007 at 2:33 pm
Excellent game. Nothing else to say, despite the fact you cannot edit your own level (and when you see what has been done for N or X-Moto it’s really a shame). Bravo !
But i got a question : it’s seem to be all about xml position and .jpg ; if i modify this, i can do my own level, can’t i? Or must i use visual basic C++ in order to fix the jpg and the (x,y) positions?
Best regards.
PS : you should sell this one to Nintedo ; it would be a blockbuster on DS !

This is a *really* idea. It would be nice to be able to change the music, triangles would be great too. I made it behave a bit oddly by adding hundreds of tiny objects. Please do more on this one!
June 29th, 2007 at 9:28 pm
Really *great* idea, that is. After reading all the comments, I’d say: at least document the XML elements so people can create their own levels more easily for now. And yes, an editor inside the game is a great idea.

Hello there!
I’m nearly done with my exams, so I think I can spend my time on this wonderful game again.
Thank you for the editor, but I really don’t know how to use it properly. I have already created another level but it was using the xml way. I’d like to make 2 other before I publish them. The problems I meet when using the editor are :
- it doesn’t recognize the levels. When I quit it and want to re-use it, it seems the file has never existed(to the editor), even if I can see it in Windows.
- Is there a way to have another background? I created some backgrounds but it seems impossible to use them in the editor.
- Can I change the looks of the static parts (still I haven’t try yet to run these levels with Crayon)?
I have just downloaded your new game but I didn’t try it yet. I’ll wait until I’m completely done with my exams.

July 3rd, 2007 at 3:31 am
Thanks for the game.
Wow, mightily impressive in its feel and beguiling in its fluidity. I don’t play games much, but I like puzzles.
I finished the puzzles pretty quickly. First I tried to carefully place things and gave up and started testing the parameters of the drawing logic. When I discovered how to insert blocks I started to really have fun. Then the long thin blocks helped me figure out the puzzles.
With both methods, careful placement and a “let’s try to break it” testing, I had a very relaxing and enjoyable time. Thanks again.
A note for all of you wanting more levels, try this:
On the last level, push off The End ball.
Make a stack of blocks on one side.
Create a catapult on the other side.
Try to land a tiny block on top of the stack.
Or set up a tiny thin block and try to knock it off.
I had a lot of fun getting things just right and a tiny block launched into the air. Usually the block just went flying off the top of screen or behind the catapult. But I finally could land a few on the top of the stack.
July 3rd, 2007 at 10:53 am
Wow, thanks everybody for drowning me in comments
First off all, about the linux port. I’d love to do it, but at this moment I can’t really release the source code. I’ll look into it and try to find a solution or someone to help me do the porting.
About the new level requests. There are few new levels here and here. And the level editor is now out so that can be used to create even further levels.
@Zuzul: Yes, you can edit the XML files and .jpg / .png files to create your levels. There’s a level editor out now which helps in that.
@Matt Doar: I’ll try to document the XML structure, when I write the documentation to the level editor. And also try to explain a little bit who the game works and how it can be modded.
@logr: Great to hear from you again. I hope your exams went well. I’ll write a documentation on the level editor, since it’s not really intuitive to use
@Jonathan: I’m glad to hear you guys enjoyed Crayon Physics.
@Tracy: Thanks for the feedback and the extra play suggestions. I hope you don’t mind, but I uploaded the images that you emailed me. I put the here to accompany your comment.

Winning point: this game made my wife laugh out loud.
My children (10,8,3) enjoyed the End screen the most, they liked bouncing stuff around without a goal. They also made the “right noises at the right time”, so I guess you could add more sounds for squares completing or lines being drawn out, or when blocks bounce into each other.
We’re glad to hear there is a level editor out!

For those who wondered, I actually solved my puzzles before I released them. I woudn’t dare to release them only to drive you mad(well, actually it sounds quite funny…).
I’ve introduced this game to some students in engineering schools (including Centrale from Paris) ad they enjoyed it too! I think you could reach as many people as the DS do ; I’ve heard on Overgame (by which I came on this site) that Nintendo was opening to Indie games. Maybe you should take a look.

July 7th, 2007 at 11:53 am
Hi Petri, I had just some questions about modding (and a few new ideas for my future levels). I’m afraid it may take you some time if you wanted to answer them all :
-in a post, there was something about sounds. But it seems to me that the only sound is the music played by the game. So if my game is bugged, is there some way to fix it?
Then, is it possible to add some sounds, for instance when the ball get the star ;
Is it also possible to change the music during a game (I mean to change the music according to the level)?
-When the ball is dropped out of screen, it returns, but it depends on which side it dropped. I wonder if it’s possible to do it with the boxes : I’ve just figured out that the da_ball command allows the ball to get to its origin. I used it with the pillar in the Log level, but it seems that the pillar will return to the origin of the ball, and is also given some rotation. Can you add a command to ensure the pillar would return to its origin, as if I used the spacebar?
-I think many have noticed that there is a way to skip a level and reach the next one. Then,
can you add a command to get to the previous level (when I want to try another way to solve a puzzle, or when I skip too many levels)? I’ve already tried to implement the command myself but it didn’t work.
-I don’t think I will use this but maybe some hackers would be interested : is it possible to use a video instead of the background? Or maybe an animated gif file? The point would be to create a level similar to the GameandWatch in SSBM (an ever-changing level), though I don’t think it is possible to change the properties of the level according to a timer. Well, if you can, I think it would make the levels more lively (although the colors already made it). For instance, it would make Tracy’s waves really moving. I thought I would create a sea-related level too.
-Is there a way to change the shapes created using the mouse :
*instead of empty boxes, could we have filled boxes too?
*then, could we change the texture of the boxes? (it would make the mods more realistic)
-Is it possible to animate the ball(like the star, added to the rotation)?
-Finally, can you do something about the black background whithin the editor : I’d like to edit a background (using Paint or Gimp), then using the editor, I would edit the level properties. I noticed there was a reference to theworld.xml and chair.png in the gfx_ressource.xml file, so I wondered if they were related to any graphics in the game, including the shape of the boxes.
That’s all I was thinking about until now. Maybe I’ll have other questions later. Thank you for reading all of this.
Since I’m done with my exams but am still very busy, I don’t know if I’ll be able to create many levels before I leave for the hollydays. I still have some free time until then…
July 7th, 2007 at 12:33 pm
I just recalled one thing : s it possible to have a save&load feature like the emulator zsnesw? I think it would enable people to solve my puzzles more easily:), but I thought more specifically about the catapult game from Tracy : people could try more efficiently to control the direction of the throw. Well, I think it is possible by editing the xml files again, but maybe some people would rather avoid this method…
July 10th, 2007 at 11:48 pm
[…] Here’s a simple, but entertaining game. The game uses some programed physics similar to what modern day video games use. You use a crayon with the mouse to draw lines and blocks that collide with the ball on the screen to control it. You can even build a ramp and slingshot the ball across the screen. The goal is to reach the start with the ball. It’s only for Windows QQ. […]

More ideas:
* a long pendulum blocking a direct path between start and end platforms. The player has to time his movement to get the ball onto the pendulum and off again. The pendulum may swing on its own, or it may need a push.
* a level with extreme friction settings
* a level with a shower of blocks falling from the top of the screen, generally messing up the player’s slower, more deliberate options. Blocks could be many and small, few and large, equally timed, fall from the same place, or be random. Shaping the falling blocks like tetris pieces would be a short-lived joke.
* a time limit–a rival ball is slowly rolling toward the star, and the player has to get there first
* closing gates that force the player to pick up multiple stars in a particular order

I think you should make a game where mouse moves around water, and you have to use the water to defend someone (clicking to freeze) and then going around something to grab it and flinging it back at whatever’s attacking you. That’d be awesome.. xD

That sets the bar for me - best game of the year. I had more fun than with line rider. Thanks.

Awesome game, I loved the atmosphere, and I was hungry for more levels at the end…I hope you make more games like this, or maybe even make a sequel, I finally figured out the shape making process, the fact that if you totally complete any shape (which creates that shape exactly) you can use custom shapes to get across challenges, not just the standard perfect boxes that spawn, very fun indeed!
Great job.

* also, the music was a very nice touch as well, it completes the whole theme, I think, and never gets irritating.

Simple and well done is usually good receipe for any creation, so i just want to say u did a great job The simplist environement and gameplay, the music , the physic … The small “bug” about drawing under the ball is not so big deal for me but the lack of level is clearly a problem.
I just said the same like most of the comments before me… but a suggestion : a level editor should bring this game to a greater success and a longer life. I am trying all the game u proposed on this blog and this one is my favorite … 200 level of it and i ll keep it in my computer for a long time ! Good job.
Really make a 1 week projet to create a level editor for it

What’s the real solution to “Sky Captain” I just drew a massive box over all the see-saws and the ball somehow made its way to the star.

I’ve uploaded the level18 on http://public.box.net/tahina795269 . For those who cannot edit the level_list.xml file, I’ve also uploaded my data folder (it only features the levels and gfx folders). You just have to swap mine and yours if you don’t want to go through editing the xml files.
I’ll also post an editor tutorial for those who want to create their own levels.

This game is awesome, but what’s to stop me from drawing tons of lines under it and doing that all the way to the star? I suggest you limit the amount of polygons at once. Also, I have a hard time making triangles. (If it’s even possible)
August 21st, 2007 at 11:50 am
really addictive - congratulations! music is hypnotic- great game! greetings from italy
August 24th, 2007 at 12:53 am
This is great! I loved the audio and the art style. My only critique is that I felt that it would be better if you were forced to propel the ball by hitting it — too often I would just be propelling the ball by creating boxes that covered slightly less than half the ball, then the box and the ball would move apart. Of course this doesn’t really mimic reality. Maybe if there was a rule that you could not create a box that overlaps the ball, it would be more interesting. But if that was the case, you’d probably need to start will the ball up high most of the time and use gravity to make things happen.

I came out of full screen and the game has screwed up my second monitor - it’s rotated ninety degrees clockwise and the resolution has gone to 768×1280 at 60Hz!
September 1st, 2007 at 11:57 pm
I got totally addicted to this beautiful little game! It’s awesome!
Is there a chancethat there are more levels to come? Please!?
September 3rd, 2007 at 12:26 am
nice game, good

Very, very interesting and creative. This would be perfect for involving kids with computers and developing other skills.

I’m sorry, I said I would release a tutorial for the level editor, but I’m moving soon, so I don’t have much time free. I hope I’ll release it within a month.

Yay this game is great, why dont make more levels?
The game is perfect, the only thing that i didnt like is that its short 
September 10th, 2007 at 1:49 pm
Here it is, the editor tutorial I was working on! I’ll just remind you that there IS an editor, and that there is already a dozen of levels available.
First of all, download the level editor pack (it’s in the june archive, top of the page),
then unzip the files :
- !!!If you want to try your level by yourself!!!, I suggest you unzip the file “Crayon
editor.exe” in the Crayon folder, among the dll files and the data folder, so as to share
the data folder between the game and the editor.
- Otherwise, just unzip the files in a separate folder; also, it will allow you to better
observe how the editor works. I recommand you to unzip your files this way.
Then you should think about your level : just draw the main parts (the ball, the star(s)
and the walls) on a paper sheet. Don’t pay attention to any background now, for the editor
really doesn’t care!
Now you can use the “Crayon editor.exe” file. You’ll first have to name your level(test.xml
is perfect, since you’ll be able to change everything when done with the editor).
When you are faced with the black screen, push S to register your level(here’s a brief
description of the shortcut keys: Left shift down (while left-clicking, of course)will
create a “static” object (which I call a wall), whereas just left-clicking will create a
“free” object (it’s the same as the game),Z adds the ball, X adds a star, S saves and L
loads).
(!!!There is one bug I came across : when closing the editor and re-opening it, it seems
the editor doesn’t remember the file (when you are to name your level). When it says to
create a new one, just answer yes. You’ll get to the black screen with the white lines,
provided you haven’t forgotten to push S before closing the editor)
You should now have two new files in the data\gfx folder : the bmp and the xml files. There
will also be a xml file in the data\level folder.
Now that you know the shorcut keys, just draw your level (don’t mind the black/white colors
until you’
