Nova 3000

A combination Between a puzzle game and a shoot-em-up, in this game you must use your 3 differently colored beams to solve puzzles and destroy enemies.

The game gets fairly hard and contains a number of stages as well as boss fights.
Space shooter that's actually more like a puzzle game. Your ship can shoot red, yellow, or blue beams and you switch between them at will. Lots of levels, 4 bosses, very tough... can you beat it?
