I have issue on the second boss. When he has half of his health left, it just goes to the middle. Then, his heads are after me. It kills me even if Iam on the other side of the map. I guess its some kind of bug, im unable to dodge them. I tried several times but its impossible.
PS: those visuals of killed zombies with critical hit are dope. I love it. Also the rocket like arms on the second boss are funny as hell. Great job, those are really interesting visuals for that simple pixel game.
