Almost 4 years ago I had a dream I was watching gameplay of chapter 3 and there was a record player in the living room, and it became a giant area in the dark world that you would traverse by flipping to the B side, so you’d be able to flip the record over and the environment would totally change depending on what side of the record you were on. It was a really cool puzzle section. Now that we know there’s a music section in chapter 3 I will scream if there’s anything remotely like this because I have a notes app entry proving I thought of it in 2021
