Day 5: Trivia

Monday, 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 B├ędard, 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.

Day 4: Photo day

Day 4 of 7 day journey to the release of Crayon Physics Deluxe for the PC. It’s a photo day.

The IGF crunch
Here’s the room in which the work on Crayon Physics Deluxe was started. Notice the huge amount of junk lying all around. That’s because it’s a storage room (at my parent’s place) used to store all my old computers and other junk that I’ve collected over the years.

The IGF crunch
The post-it notes contain small TODO lists. This is taken right after I submitted the game to the IGF. Two weeks before this there was only one post-it note on the monitor.

The Old Bastard
Picture of Old Bastard. Compiling the game on the old bastard takes a little over hour.


Post-it notes from the last two weeks of development.

Day 3: Prototyping Crayon Physics

Saturday, January 3rd, 2009

Day 3 of 7 day journey to the release of Crayon Physics Deluxe for the PC.

I was going to post this small segment from the talk that I gave at MIGS few months back. It explained how the prototype of Crayon Physics was created and what the influences of that game were. Unfortunately the audio quality of my MIGS recording was so poor that I couldn’t get anything useful out of it. To fix this problem I re-recorded the audio and slides. Unfortunately when I recorded it by myself it came in twice as long and way more boring than the original.

(I have to apologize for the poor production values).
