I stumbled across this little gem of a game called Crayon Physics over on the excellent experimental gameplay project website. The game’s author, Petri Purho, is currently working on an enhanced version called Crayon Physics Deluxe for commercial release “when it’s ready”, but in the meantime this prototype he made up in 7 days is a blast to play around with.

The purpose of each level is to get a ball from it’s starting position to a pre-designated target area. Players accomplish this by drawing ramps, bridges and whatever else they can think of to help the ball on its journey, then dropping a square on the ball to get things moving. Once the ball is in motion you can still draw squares to help it on its way, but for the most part it’s best to have everything drawn up before you start the ball rolling.

Unfortunately, in this early version of the game, players can draw whatever they want, but in general the game will automatically change your drawing into a square of a similar size before dropping it into place. This is, of course, a pretty major limitation, but for a game made in under a week it’s still an impressive feat. Petri promises that Crayon Physics Deluxe will have no such limitations when it releases.

If you’re looking for a fun way to waste a few hours, give Crayon Physics a download over at Petri’s blog. While you’re at it, take some time to explore the site. He releases new 7 day games all the time and a lot of them are really cool.

By the way, if this prototype isn’t enough to get you excited about Crayon Physics Deluxe, check out this amazing video of the game in action below.
