Crayon Physics Deluxe Demo and FAQ

January 8th, 2009

It's here! Crayon Physics Deluxe is doneYesterday the full version of Crayon Physics Deluxe was released for the PC with a bit of cryptic blog post. So I thought I’d answer some of your burning questions by providing a demo and a FAQ.

So yes, Crayon Physics Deluxe is finally here. You can go and buy it for 20$ from here. Or you can download the demo and give it a test.

There’s been a lot of questions going around about the game so I though this would be a good place to go through some of them. It’s sorta like a quick FAQ about the game.


What are the system requirements of the game

Windows XP / Vista
1 GHZ or faster CPU,
512 MB or more RAM,
DirectX 9.0
3D card with 128 MB of texture memory

When in doubt, you can try the demo to see if it runs on your system.

Is there a Mac / Linux port

Unfortunately not at this moment. I’m planning of doing these as soon as I’m done with the PC version of the game, but I can’t promise anything at this point.

I bought the game but I didn’t get my download link

Day 5: Trivia

January 5th, 2009

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.
