That's really nice to hear!
I love celeste, and I guess it shows :D
I will try and expand upon the basic mechanics of the game and see how it goes. I had a few things in mind I didn't manage to include in the jam.
As for the audio bug, that's really interesting, was it after you take a flower?
Right now the music updates at 1 flower, 5, 8, and 10 where it eventually stops, so I guess something over there.
