wave 11 was the first time i got hit, nice game, only drawback i can see is how your ship doesnt pin to mouse very strongly, i use a very high sensetivity mouse and i could go back and forth on the screen with my mouse before the ship moved at all 4/5 though nice work
badges are ahrder to intergrate than you might think, they take time, if they are even being considered, (which im certain they are for this) so just cool it and wait
has potential, if the movement was slowed down a bit, a menu added some sound and the ability to die, then it would be a good game, still decent though, nice work.
