This game is seriously freaking me out! Zombies spawned out of nowhere, coming at me quite fast and with quite a lot of HP, and the 3D sound effects just make it a lot more realistic. It really had me on edge like I am in there with a bunch of zombies. I didnt quite get the theme in here but it was fun overall, in a sense that I know I was getting better at it. Local highscore is a nice touch, I got ~1500 in my 3rd run. Great work!
