To start press the play/pause button. The ball will glide left to right following your mouse/finger while continuously slowly falling. It will bounce on the platforms with black outlines and fall fast when touching anything red. There are boosts which look like yellow circles with arrows in them, which will also change your score. (The score you end with is the how high you are + the "+" variable squared) (you can use the boosts by pressing the up arrow or clicking on the giant boost symbol in the bottom left corner) ...and that's it! ___________________________________________ Tip: If your mouse/finger is over the red platforms or balls, they will turn black and you can bounce on them as well. :)
