bro ProjectSG, in every game the walls are invisible from the other side, how do you think one side of the wall can be... idk, bricks, and the other side maybe wood in plus, or maybe, in classic remastered, you know the walls that are faces (Noncannonconnorwall)? Well, the way that's made is that they are invisible on one side, so really, in between rooms are 2 walls. So like, the hallway has one wall then the room on the other side is another walls, so 2 walls put together look like one, but they are really 2. Get it right XD
