Okay I loved that one, insane job. I have to say though that the sniper might me a bit too powerful, I was able to get a 3:04 thanks to it (suicide twice to get the sniper and camp the top platform with it).
My only minor complaint would be that WASD are the only controls available and I don't have a qwerty keyboard, so maybe allowing the player to remap the controls or something like that would be a good idea, nice!
