I really like the concept, I love the artwork and the audio, the racers are colorful and pretty fun and goofy, I love that. Game-play wise is a bit too confusing, maybe better start with a few runners and introduce the abilities level by level, so you can smooth out the difficulty a bit. It would be also useful to see where's the head of the race, or which are the first three racers, maybe add a contour to the racer at the head. Fun game.
