Day 5: Trivia

Day 5 of 7 day journey to the release of Crayon Physics Deluxe for the PC. It’s trivia day 🙂

Did you know that:

  • Crayon Physics (the prototype) lacked a bunch of features, because I locked myself out of my apartment and lost two days of development. I couldn’t get access to the computer that had the source code until June 1st (the release date).
  • Originally I started working on a bigger version of Pluto Strikes Back. It wasn’t until the second week of development that I decided to start working on Crayon Physics Deluxe. Reason for the swap was that I thought I could do Crayon Physics Deluxe during the summer. Oh boy was I wrong.
  • The only reason I started working on Crayon Physics Deluxe was to get a free pass to the Game Developers Conference. I figured that I could do something that I could submit to the Independent Games Festival and get in to the finals, because if you’re an IGF finalist you get a free GDC pass.
  • I changed the physics engine of the game, one week before the IGF deadline.
  • Crayon Physics Deluxe destroyed my education. When the summer of 2007 ended I took a 6 months break from school to finish the game. When the game made it to the IGF finals, I decided to take another 6 months break. After the summer of 2008 the game wasn’t still finished so I had to take another 6 months break and eventually another one this January. I doubt that they will allow me to finish my degree.
  • The name “Crayon Physics Deluxe” was picked when I was filling out the IGF submission form and it had an input field for the name of the game. I had to modify the title screen after submitting the game.
  • I was disappointed when Crayon Physics Deluxe won the grand prize at the IGF. I wanted World of Goo to win, because I think it’s a better game and because Kyle Gabler is my idol.
  • During GDC we stayed in the same hostel room with Phil Fish and Renaud Bédard, the developers of Fez
  • My mother wasn’t too impressed with Crayon Physics Deluxe, she told me that the game looked like a five year old made it. And I should have used a paper that wasn’t all wrinkled and I could have used a ruler to draw the lines so they would have been straight.

    This is inspiring Petri. To find out that my idol idolizes my other idol! It makes you seem human. It sounds like you’ve had a wild ride. I hope it’s downhill from here for you 🙂


  2. Intamin Says:

    Love the comments from mother, Petri, haha. World of Goo is fantastic and both games are wildly inventive.

    Keep up the great work.

    Hey Petri, reading your post made me remember the good/crazy times spent at the IGF… Still haven’t forgotten your splendid acceptance “speech” hehe…

    This reminds me, were you going to participate to that games exhibit in Queensland? I saw your name on one of the emails but don’t know if you followed through with it.

    You got better at blogging this year, better than me at least 😛

    Nice stuff. This is my second favorite day of crayons!

  5. Matt L. Says:

    I laughed when I read your mom’s comments on the game.

    P.S. Yeah, World of Goo is pretty amazing isn’t it?

    Upealta näyttää ja tilaukseen meni! Sano äitilles terkkuja Jaani-serkulta 🙂

    p.s. osaatko suositella hyvää piirtopöytää? 😉

  9. Olle Says:

    World of Goo is great aswell but I like CPD more 🙂

    Ps. Just finished the game, awesome work!

  10. Chance Says:

    Hey does anyone have any news about Fez? I am really interested in it, but there doesn’t seem to be anything going on. I mean, they made it to GDC, why would they stop development.

  11. Petri Purho Says:

    @Balthazar: GDC was awesome. Are you going again this year? I’m not sure about the Queensland thing though. Probably, but not 100% sure.

    @Jaani: I’ll tell my mom that you said Hi 🙂

  12. Phillip Wells Says:

    Been looking forward to your game for a long time. Do you have any plans to make it available via Steam?

    […] attempts. In a way, this is elegant on the part of the game’s sole designer, Petro Purho. His factoids on the making of Crayon Physics Deluxe are a deft blend of commentary track and comedy of errors. E.g.: “The only reason I started […]

  14. Teemu A Says:

    Petri just give Simo a ring and return Crayon as your Thesis. Have you written any documentation about it? I think you would get it pass as such with a bit of documentation. It is ironic that all guys who finished their education wrote such crap software and you wrote something magnificent and didn’t finish. But I guess that is just the reality of IT business.

  15. ROuNIN Says:

    Hello Petri,
    Please try to get your education finished, I know that the silly piece of paper just proves that you can be taught by professors/lectures at University/College! 😉

    Best of luck!

    @ Petri: I don’t think I’ll make it to GDC this year, I have a prototype deadline on feb-mar for a new game and I really wouldn’t want to miss that. Now, if ubi pays me to go I won’t say no, hehe… I’ll probably be attending Paris GDC this spring though, maybe we’ll meet there, now that you’re well on your way of becoming a gazillionnaire 😀

    Now that CPD is released, will you get back to making monthly prototypes? I really really enjoyed those. Anyways, nice talking to you, as always.

    oh jeez, now I feel guilty…
    I was so pleased when the email came in, installed the demo, played it right thru,
    even tho it’s midnight and my wife is waiting for me in bed 😉
    gonna buy the full game tomorrow with my (2nd grade) son,
    who’s gonna be ecstatic… (He plays the old demo all the time (me too))
    and now I see the game is messing up your education … aw heck …
    It took me ten years to get my degree while working full time,
    so I know it’s tough. Hope they’ll accept the game for mucho credit or thesis.
    Hang in there and Thanks!!

    I discovered your game while listening to the interview you gave on Houston Public radio. You are a true artist, I love CRAYON PHYSICS, and I know the children at our school will love your game. It is a pleasure and an honor to buy this game from you. Continue your passions, everyone is a better person because of your work. BRAVO!

  19. Riley Murphy Says:

    Great job, I can’t even begin to understand how you coded this.
    A true piece of art.

    One suggestion I would make…is to drastically lower the price. You’ll make a cr*p load of money if you’d only charge 5 dollars for this game…Might sound insulting, but think of the economics of it. Most people wouldn’t bat an eyelash at spending 5 dollars (like myself). But during these ‘interesting’ economic times (where the game industry still seems to be staying strong), spending $20 on a game causes me a certain amount of hesitation. I might just be cheap though.

    Seriously, your game is going to spread like wildfire – the demo will anyway. You might as well improve your chances of making an obscene amount of money off this thing by lowering the price. I read that some stupid farting iphone app that costs $1 made $40,000 for the programmer in 2 days….This game is no farting app….Just throwing this idea out there.

    Thanks again for all the hard work.

    Good luck!

    You did it! Crayon Physics Deluxe is a real masterpiece and one of the greatest games I’ve ever played. You showed to the world that even a single person can create a computer game that is as much fun as the most expensive games the industry produces. Keep up the good work!

    Haha, I love your mom’s comments. They sound just like things any mom would say. ^^;
