Arrow keys to teleport! A and D to move! Space to attack! E to spawn waves! Press the S button on the left to buy upgrades! The point of the game is to get to the highest wave difficulty possible, you can do that by spawning waves, and killing all the balls before they get to the eye!
Thanks to Minecraft for the ender idea! inspired by PvZ for the wave and turret idea! Note to self: add a jump button
