Wow, the game is actually pretty fun. I really enjoyed killing zombies, it fits the theme really well. The art and the sound works well for this game : it is VERY good !
The only downside would be that the camera is too zoomed in and I feel really "stuck" in it. Also, what could have been cool, would have been to have an input setting menu, because it was pretty hard for me to play as an azerty user, haha !
Anyways, awesome work, hope you'll keep on going with this game ! :)
