I believe that it would be a good idea to make pianos interactable, so that when you interact with it, it plays a random piano note. Pianos in the game at the time of posting this are relatively useless. This would be a nice addition to make the piano not as useless, and it definitely would make the game that slight bit more immersive. While it's not anything super important or game-changing, I think this would be and interesting addition to the game.
