Really creative game!! The art style and music are both wonderful and the ideas are super fresh!
I am nitpicking here because I think it was amazing but could be even better with a few small tweaks: I wish the map had a few more defining features to it. I wanted to memorize the layout of the map, but there was really nothing to use as a point of reference. Placing the camera a bit higher and a bit more tilted down would allow you to see incoming obstacles a lot easier. Being able to see obstacles on the underside of the road was pretty distracting. Either culling them or adding a shader to the road to make them blurry would take the game a long way.
Keep up the amazing work though!!! I enjoyed it a ton :3
