Okay found a glitch. If you turn backwards, let a zombie hit you from behind and spam 'S', the game freezes and you can not play anymore. Also I feel like the only way to let the zombie close enough to striking distant is to let it hit you, Perhaps you could make the sword longer? Anyways all in all its a fun game and the animations are really good!
Added to the Bugs List ! When you are close to the zombie , you have more or less 3 seconds to hit and run from it without get damage
its a fun little game to spend some time on but sometimes the zombies should be a little faster
Every single generated zombie has diferent speeds, some of them are fast, and some of them are slow
