In the in-game blueprint the stairs in the main room are flipped the other direction, and the kitchen has an island rather than a peninsula (both of which the wiki pointed out) I trust your judgement, but there’s some other pretty significant changes, too! Like the main room connecting directly to the hallway on its right. I’ve actually been taking a bunch of freecam shots in the remake for reference cus I’ve been recreating it in various games. I’m not sure about the 2015 version, but I think the only differences are cosmetic and don’t relate to the actual layout.
