An Amazing Marble Race! Root for a marble of your choice, and there is elimination so no switching! To start the race, press enter/return. To start the next leg, press the number of leg that ENDED. For example, to start leg 2, press 1. Drag alongside the marbles as you go! I tried to make the teleporters as close as possible to avoid missing marbles. (EXCEPTION: THE ROPE. LEG 7.)
(NOTE: some thing I had to look up from other people, like teleportation, but the legs are completely my own, unless by coincidence. Thanks!)
If the marbles get stuck, use the Drag Tool to move them. I suggest hitting "d" before hitting enter.

Enjoy the race!
