basically, use arrow keys to move, space to attack, and avoid zombies. When you kill one, you will see that the amount of zombies you have killed will go up. try to get the highest amount! Plus, you have a timer. try to survive for the longest amount of time. (P.S. Double click the flag or your pick-axe, your weapon, will drop and you may never pick it up ever again, or you may not be able to move.) Try to beat my time of 47.03 seconds and 32 zombies!
