Prevent the enemies from overrunning our world... yes, yes, our world looks tiny and weird, much like a video game level. Anyway, where was I, oh yes! You must defeat the bad things entering our world via the wormholes and destroy the wormholes as well. Only you int your purple capsule thingy can prevent further bad things coming through.

Use the controller if you have one, otherwise wasd for movement and ijkl for shooting. control/fire1 for bomb action.
