You might get some more eyes on your game if you released it on Itch. It seems to me that it would fit better with the gamejam scene than general consumption.

With my amateur game design hat on (discard if you please):

I think that the game could be much improved with a drum track to make playing the game feel more zen. I get the vibe that it isn't a game that you "play" but more of a time killer.

It would be extra cool if the audio effects could play in time with the drum track, too. The player could be composing a song as they play.
