Use the arrow keys to move and click the mouse to shoot. Avoid the zombies!
The variable Score means what level you're on. Please comment for any suggestions or complaints or glitches. If this project gets over 5 likes and/or favorites, I will make different levels, more upgrades, different zombies, more gun types, etc. Happy Halloween! Edit 1: I have fixed the glitch where the gun goes through zombies without killing them. I have also made it so the bullets can't kill multiple zombies with only one shot except for every once in a while. Edit 2: New gun type. I am now playing with the idea of different zombies: bigger ones that are harder to kill, faster ones, etc.
