i havent seen anything about this on here yet but there’s a new Steven Universe app called Soundtrack Attack !! its free for both iOS and Android!
its a rhythm game where youre a gem thats come to earth to escape the diamond authority! the songs are all fun remixes of songs from the show!
you get three slots (a quartz, pearl, and ruby) and each is its own separate save file. you can customize your player pretty well, and win coins in the game to spend on accessories and different haircuts etc.
im on mobile so i cant link but looking it up in your app store should work! its a little challenging but fun!
