Every replay is different, every change or direction creates a random new set of threats around the player. Nothing is the same, and nothing is predictable.
Enter "Endless Mode" to hunt the biggest high score.
And remember, do not collide with "The World Killer". Any collision with him is game over.
Starting as an innocent asteroid your goal is to evolve and progress to larger stages. Collide with smaller asteroids and evolve to the planet stage.
