When you click the green flag, the game starts right away. If the ball is on the edge, it takes away one of your points. You can see your points at the top left side of the screen. If when the ball touches the edge and nothing happens (like what happened to me), reload your computer.
I think this is a harder version of the pong game made by the step-by-step guide. I thank the step-by-step guide in helping me make this game.
