Follow the ball with the mouse and get to 100 to beat the game. It's incredibly simple. You shouldn't struggle. It does glitch a bit and doesn't count all the points you should have but it works eventually. Consider yourself a winner if you get over 100! Feel free to remix it. You need to mention me as the original creator in the credits, however.
^_^ I made it BY MYSELF. Time I spent on this: 5 minutes and 23 seconds.
