My biggest complaint is that it is too short.
I love the idea of the enemy manipulating the canvas, its very creative.
However, it only lasts a couple seconds since you only need to land 4-5 or so shots to kill the one enemy this game throws at you.
Because of this Ive played it 3 times and as far as i can tell its more space control and not really time.
Still a great concept tho, and as the rest is your typical top-down-space-craft-shooter its a very solid game.
Really good job on this one.
