Nice game. I killed 512 zombies, the airstrike is so satisfying haha.
I have some criticism: the movement of the player is kinda weird, sometimes it goes slower and sometimes really fast. The area of effect of the abilities felt pretty small to me, the "pull" and "push" did not make any real effect. The enemies do not "upgrade", neither your gun, that makes the game kinda repetitive.
I understand that this is only made in a week, and I'm only trying to help for your next games :)
Still, the game is pretty fun to play, congrats man!
