Thanks for playing! Yeah I agree with you, the current way rerolling is implemented is kind of a band-aid fix for how random the tracks are that I meant to eventually replace. But as you see, I couldn't come up with a better solution during the time I had lol.
Thinking about it now, I think the game would probably work a lot better if A) you could rotate pieces, and B) each track "piece" took up multiple tiles (So like S curves and stuff). That's probably at least a little closer to a better system.
