Super fun Racing/Platformer hybrid, i really liked zooming around and it's a lot of fun when you manage to keep the momentum going. Pixel art is super sharp and very well animated, and the music is really catchy.
The only tiny issue i'd say would be that with your white level blocks, it can be hard to read when you get a super bright colored background, like the yellow section, maybe have the ground colored as well and change the color to something that pops accordingly to the background color.
Other than that its solid overall and the course itself had a nice variety of obstacles slopes and what not and was fun to go through.
Well done :)
