Loved your game! Is super cute! If I may, I only have 2 humble suggestions. One, it was a bit hard to differ between the racing track and the walls. I would suggest making it a bit more clear so that players are not constantly hitting walls. The other suggestion is to make the camera a bit more wider so u can see the path forward? It was a tiny bit hard knowing what was to come, but I think this is def a more arguable suggestion.
Overall amazing game!
