Its kinda fun!
I like the overall aesthetic, and the premise of having to spam E on a spot while a bunch of enemies try to kill you is good, that being said some the mecanichs do lack a bit of polish. For example, I didn't really get the point of the punch, evey action the player can to do should have its own strengths and weaknesses and should encourage interesting decision making. Also the enemies can't really do anything if you play super defensively (get a couple hits in and immediately back out), passive healing is a very dangerous mechanic!
Overall though, its a fun game, good job!
