The game is simple and enjoyable. Nicely done creative idea to use the spin to get boosts but I think the game would have gained a lot by making the tracks less squary and adding free movement instead of simply the x or y directions.

I see i do understand the vision for the tracks then and I love the approach (maybe you could have left the squary visual aspect as it is while rounding the collisions ?).
What I meant by free movement is that right now you can only go UP, LEFT, RIGHT, DOWN and I feel like it clashes a bit with the spinning mechanic thats lets you freely rotate your mouse in any direction. I don't know if I am clear enought sorry I am quite bad at explaining my thoughts.
Still you made a pretty nice game well done ^^
