The space pussy has to defend the humans of dangerous asteroids. Shoot the asteroids to tiny pieces. Try also to kill the evil Cat head in the sky. Also, there's a SECRET in wave 5 and 10. Why don't you try and get there. It's a really cool secret, promise.
Shoot all the asteroids to continue to the next wave. Try not to get hit by one of them, they hurt :( Oh, and try to rescue those poor astronauts. Maybe they'll give you some points!
A context menu should be shown when right-clicking or, on touch devices, long-pressing in the game. This menu especially allows to play in full screen and control the volume.
