Just made this to see whether I could. Not one of my best games, I know :P Use the mouse to point and shoot the horde of zombies coming for you. You can only hold 10 bullets at a time - when you run out of bullets, you should press the spacebar to reload. This will take 3 seconds, so be careful! Note that you can't reload if you still have bullets.
