I play this on the browser of itch.io. I gotta say it's a very cute game. The concepts are really simple. It also gets you in a very calm zen-like state while playing.

There's not really a bad thing to say about this, but I feel like after going into the instrument it is better to have a countdown to start the rhythm part at a new beat, because this part kinda throws me off at first. Another thing is just that maybe it should be a bit smoother, but I play on the web version so what do I really know haha.
