Zippy Zombie Zebras

Can you defend your base against the waves of zombie zebras? Terrible mutations have occurred due to radiation from the apocalypse. You begin each round with full health and 50 cannonballs.

• Fire when the zebra is intersecting with the circle (if you can barely see it, you brought this upon yourself by using Safari/iOS).
• You can use the arrow keys, WASD, or a mouse/touchscreen (far easier on keyboard, though).
• This game does not compensate for Bluetooth delay.
• Some of the timings are really bad.
