Brilliant idea.. It took me a bit time to figure out what to do but this concept can be very interesting. Looking forward to see a polished version.

Mainly UX, it took me sometime to realize that i could hold pressing the key, initially I was pressing and releasing.. Things like that...
But also some levels can be refined. For instance, in the first level there is no need to wait for the recorder after it passes the key. It feels like wasting time since it does not contribute to creating the platform. With a more cosy vibe (stardew valleyish), this game can be a really calming, wholesome experience :))
