The game has no levels, each time for you to be infinite, however, until until you do not get shot. Watch everything happening you with the top view, where you can see your own character, and enemies attacking from all sides. As soon as one wave of enemies will be destroyed, the level immediately rebuilt and a new wave of enemies stronger and more ferocious.
