The buttons may confuse some people, so here's an explanation: Up Arrow: imports a circle via a code Save: gives you a code for the current circle Restart: same as green flag; makes a new circle Auto: toggles Auto Mode, where a new circle is created after the current one finishes Turbo Mode (shift+green flag) is cool, but I don't recommend it when Auto Mode is on.
I came up with a way to make cool circles, and this is what I came up with.
