Nice game. I had to learn first that I have to kill enemies in order to get points for moving and I don't know if it matters but I charged "turrets" from A - D. Even so, the game didn't end so I expect there was "turret E" somewhere. Graphics is good, audio also, maybe focus (red light) is a bit strange. I think there is a bug, when you stay outside turrets and kill all enemies, no other enemies spawn? All in all, this was very interesting game.
I would like to ask you to rate our game too, if you have spare time, sice we haven't enough rating yet :)
