I remember your game from an earlier test version! Was looking forward to the finished version and now I finally got to play it!
It has a very playful, bright and all around fun aesthetic, kind of like a racing game spin-off of Parappa the Rapper with a touch of late 90s Paint Deluxe doodles - love it! Also stays true to the original cartridge, while still adding a personal note.
The music is simple, but supports that playful atmosphere pretty well. The change for the last round is also a nice touch.
Didn't get to play it in multiplayer mode and only finished 7th or lower, but it was still pretty entertaining to play it. I think a couch co-op session would be really fun!
