Buzzball: real hamster ball
You still remember hamster ball? It is a horrible video game; you need to keep balance while running by typing the arrow keys. If you are good at it, you might think it is a piece of cake and need some harder stuff. Then I think you will like this.
What you have to do is sitting in this so-called buzzball and drive it with the two trigger. Oh, sure, you have to close the door. Then you will have a chance to play a real hamster ball, or we should call it human ball.
