XXI Billiard

This is an unusual billiards game with some new rules. The balls roll without any friction and they don't stop! You have a time limit of 15 seconds to try and get as many balls in the holes as you can. So, push the red ball and try to hit as many balls, before the time's up. When 15 seconds pass, you see your score. After it, your opponent plays. If you scored more than your opponent, you go level up, but if your opponent has a higher score, you go level down.
