Your task is to guide Marvin and his insatiable appetite for celestial bodies all around the galaxy, chomping up planets and meteors. Stars are a little too hot for him, so be wary of those!
Three game modes! Normal Mode, where Marvin's speed increases with the number of tasty planets he consumes, and Two Player Mode, where you can challenge another player. Oh, and Zen Mode, where there are no speed increases, so you can kick back and enjoy a relaxing bit of mass geocide.
The controls are just the arrow keys. If there is a Player 2, then they can use WASD to move their world devouring snake.
