The music is absolutely fantastic. The art style is very charming and does a good job of mixing the mutations. Overall super solid game, my main feedback would be with some QOL things as well as UI/UX.
It feels a bit odd to have to click on View Racers then Start race again. I feel like "Race" then "Start" would communicate that a little better. Not a big deal, once you understand the flow it makes sense. Also I wish there was like an accept mutate button for the mutations rather than having to go back to the menu then come back in.
Would love to see more mechanics, maybe more stages/challenges. Super fun!
