Hey you! Yes you! Have you ever wanted to be a stick figure that has a head that looks like a potato? Well, you found the right game! You just make him move around. And let him dance. Use the arrow keys or something to move him around and yeah... Also, Flatman is kinda dumb, so when you restart, he may be in his previous position.
Don't press the "D" key. Just trust me on this. Don't.
