use the arrow keys or WASD to move. use your mouse to aim, and shoot. Every time you shoot a zombie you get 10 points. You have 5 hearts. When you touch a zombie, you lose a heart. If you get a health power up, then your hearts go back to 5. If you get a gun power up, then your gun gets an upgrade!
I got the buttons form a project by @Frogleg8. I am working on the shop and tutorial. The outro is broken. Wow! 270 views!!
