Overall I liked this game, I found that it's gameplay was simple enough to be entertaining for a while, the most interesting part about the game is the fact that the entire 3D raycasting engine and game engine are compiled into just about 10k of program space, meaning this is a very good example of a light weight 3D engine on this small platform. It does get boring if you play it too much, but if you are in the mood for it it can certainly help you pass the time. I recommend downloading it, if nothing else just to see this wonderful implementation of raycasting.
