You are a square on a torus. Use the arrow keys to move. The variable kB? will control whether you are on a klein bottle or a torus. For fun, the background is the Mandlebrot set. Use the different costumes for "Level" sprite to change what the torus looks like!
This is not a game, but a demonstration. For more information on tori: https://en.wikipedia.org/wiki/Torus The inspiration comes from the book "The Shape of Space" By Jeffrey Weeks
