This is fun, can't survive till the zombie king arrives though sadly. The game is quite smooth, and adding in style points is an interesting idea. (Seldom use that though) I'd say the slightly to the right aiming is a huge bummer and I can't count how many times I died due to this alone (not counting the runs where I don't even know this is a problem). I am also having a hard time judging how many shots I need to shoot a zombie until it's dead, one for the crawling ones? and three for the walking ones? I just don't know. Any indicator will be better than shoot and wait till the animation ends. I got ambushed a lot from the back by newly spawned zombies, which I think is a bit unfair as there is no way to tell if there are any zombies behind you. Leads you to panic shoot quite a few times. Speaking of shooting, I also felt the bullet count was a bit harsh too, I ran out of bullets a few times and died because of it.
Anyway, apart from all of these, the game is still quite well made! Nicely done!
