Use p to toggle off and on, along with lower spawn rates. Use the Arrow keys to choose the spawn location. WASD Changes X and Y change for clones when they spawn. Q and E edit the "Flip" of the "track". Use Space to randomize WASD and QE. Hit 0 to make the track rainbow Hit 9 to make the track only one color
Funnily enough, I tried to create a procedural track spawning, but I can't code.
