The 100 Zombie "Challenge" v3!

Lower the zombie's health by clicking on him. He has 100 health. Kill him to win! He will slowly creep to you as well. Don't let him get you! Edit: In v2 when he reaches 50 health he will throw deadly fireballs at you! Press space to dodge them.

Edit 2: In Hard Mode the zombie is slightly faster and fireballs are thrown more frequently. Can you beat it? I did. You can do it!!!! <3

Edit 3: The boss in Story Mode has the same mechanics! It's still space to duck- but you actually jump.
