Click the green flag to begin. The only thing you have to do after that is press and release space with good timing. When you press space, the green circle (you) will reach out for a node (the yellow things) within a certain distance. Once you get to a point where you're moving tangentially to the circle created with it's center on the node and you a point on it, you will begin to orbit that node at a fixed distance. (if that last part didn't make any sense, just try and figure it out while playing) To stop orbiting a node, just release the spacebar. The goal of the game is to see how far up you can travel, but if you run into the walls and you aren't in orbit, or you actually run into any of the nodes, you lose.
