The TiltMaze game started as a SnakeQuest level set. One day I got the urge to remake it as a standalone program seeing as SQ is no longer in development but most of all because I made 22 decent levels for it, and they aren't easy to make.
To play the game you 'tilt' the board up, down, left or right and all the balls roll in that direction, you have to put red balls in red holes etc etc until the board is cleared. Like all sokoban style games the fewer moves you can do it in the better.
Thanks to BinarySpike for the level abnormal! Email me good levels you make if you want.
You can download the game (universal binary) or source code here.
