As others have commented. The race itself is too slow. It would look like slot cars if it was sped up! Music is sweet and game looks really nice all around. Cool premise!
I struggled a bit in the beginning, mostly because one of the pieces is off screen and I missed in the description (more than once embarrassingly) that we had the ability to move the camera.
But all around, good stuff! The idea for the game is solid in my opinion and would totally play that.
