Cool idea. I was thinking of a similar thing, but ended up doing something completely different :D
The gameplay is really nice and kinda relaxing, which blends great with your awesome choice of background-music.
The jumping- sound you chose can get a little annoying, especially since the rest of the game is pretty chill. I think I would remove the jump-sound or make it VERY subtle and add a gong-like sound to the reset-mechanic instead.
I really enjoyed this!
