The into was really cute, I fell in love with the protagonist, even if he becomes a disembodied arm later in the game. I agree with Nanbaya: the music was pretty chill, which I don't know if that's what you want. The letter placing felt ok, but if you doubled down on flicking the mail, that would be great. The symbols on the letters were a bit small to be able to see them easily, but the colors helped a lot. Also, I love that it feels grounded in a specific region of the world, because we need more representation in games.
