I started this as a test of my marble race building abilities, and the first half is an attempt to copy "simple marble race" by the youtuber, MIKAN. In the second half it kind of evolved into its own thing. The green ball in the bottom right is the finish line. It teleports the first, second and third finishers to the gold, silver and bronze cups on the right. The fourth ball to hit it makes it disappear. Feel free to copy this as long as you give credit. Enjoy
