how to play: move your mouse, to control a green ball, YOU CANNOT TOUCH THE BLACK OR YOU WILL LOSE, you need to make your way across obstacles, and collect all of the keys (the blue balls), there are 3 of them. Then you need to make your way back to the flag and click it to move on to the next level. There are currently 5 levels. controls: Z and X allow you to change your level (you can only choose levels you have unlocked)
