Game's working fine on Firefox 107 Windows 11.
This is an interesting concept. It seems tuned well, since I was usually able to place 3rd-5th on my first few races and it seems like with practice I could do better. On the other hand, I felt like the game suffered from a low-ish decision density - most of the time it made the most sense to follow the highlighted path, and while I could walk another direction I couldn't see why I would. Seeing a powerup off the path fixed that now and then, but it didn't seem like there were very many.
I love how many themes there are though!
