Cute game and fun interpretation of the focus/ theme! I love chill puzzle games and the music is a good tune that you don't mind listening to on repeat.
Edit: SUPER fun after I figured out the reset puzzle button! :)
My suggestions and issues I had:
-Make the "human" a different color than the stones. I didn't realize he wasn't a block until after a few tries, so making him maybe "flesh" colored or giving him an idle breathing animation would show people he is the other character.
