I got a funny ranking
Hah, I'm 69th ;P
Graphics: Great effects, have you considered maybe making chain-reactions using debris? Love what you have here though.
Style: Simplicity gets a ten from me.
Sounds: I didn't have my speakers on, but this kind of game doesn't really need much.
Violence: Eh, I'll give it a seven only because it's mass square murdering
Interactivity: Obviously a ten, but consider toning the speed down a bit, my wrist hurt by level 50.
Humor: Killing squares is funny, so getting a five is good for a game.
Overall: Ten, I loved this, it was worth my time
Looking forward to more games :)
