I spent like half an hour making Gourmet Race from the Kirby games. If you see brackets {} then it means you need to play it twice as fast, and if you see double brackets {{}} then it means you need to play it four times faster. This song is harder to play than any other song currently in the Playable Piano since there is some places where it quickly switches between eighteenth and sixteenth notes.
Here is the sheet (Yeah, it's really compact)

P.S: If you add this sheet to the Playable Piano or another version of it, I would appreciate if you credited me
