This is a neat little game.

Its a cool little 3d game with a little but of physics involved, or so it would seem from the screenshot.
You are in a room that has graph paper as the wallpapers on all walls, even the ceiling and the floor. Your objective is to bounce the ball of a wall and hit each block...changing their color from red to gray. Your objective is to complete the level with a positive score.
Every block you hit directly is 10 points, every block you hit off a wall is 100 points, while every shot you take is -100 points. There are also some other guns which have a higher cost.
You can knock blocks from under a stack and have the ones on top fall off to change their color.

Its a very simple concept, however I'm a man with very low patience.
Once I figured out you could shoot a single block and just push that around to knock the other blocks from red to gray, thats all I did.
You COULD push the red ones, but you get penalized a boatload. There is no penalty for pushing a gray one into a red one though :). It made the game go very fast :).

There are 39 pre-built levels for the single player game.
No multiplayer, however you can download new maps from the homepage or build your own if you are so inclined.

The game is well done. Its worth the download in my opinion.
