Excellent :)
Loved the game, loved the whole concept, 1 thing annoyed me though. The sound that the little red spinning laser-ma-thing was making, that drove me insane! :P
Couldn't stand it, so I turned off the sound and cranked some Death Metal >.>
Any how, great game, loved it, and well, yeah :)
By the way, the last level wouldn't finish for me.. I eventually got up to around 400 kills and just quit the level >.> Was that meant to be?
Any how, keep up the excellent work :D
