Save the universe from paint blob monster thingys.
This is a solid shooter game, I like that killing enemies can reveal the tiles, and the limited ammo require you to ration ammo between revealing maps and shooting enemies.
The art is very nice, I like the cartoony art style with heavy inking.
Only complaint I can think of is that dieing at the second stage resets you to the beginning, that's a little too harsh. Maybe some checkpoint system would be nice.
The boss fights are also a neat cherry on top of the cake.
