I think A for going back will be better than Q. Knife cant beat zombie so when u are out of ammo you are basicaly dead. But all in all pretty nice game, i wish your luck. GL with your project.
Yes it's designed for AZERTY keyboard for the moment.
(Im french, I hadn't even thought about other keyboard users until the first comment below, so i'll add the possibility to bind key).
Knife can kill zombie, it has damage location as same as the gun with less damage of course, but I need to rework his hitbox and animation.
Thanks for the review.
