Crayon Physics is a game by Petri Purho, a student attending Helsinki Polytechnic. He’s a very prolific game developer, cranking out his tenth game, each game developed in under 7 days to force him to be productive and to learn something new.
He’s looking for criticism to improve his coding skills at developing games, so help a brother geek out. Download it (5 MB), test it, give him constructive feedback.
Here’s a demo of the game via youtube.
