Dude, something's been driving me crazy about this game for years. Sorry, but this will be a long one. Okay, so on Chaos Island when you get to the top of the island you'll find Chaos Temple. Go inside and clear the first few rooms. Then you'll find this sort of circular alter room with a few enemies, the room/area I'll be talking about is directly after this room. The room/area is a hallway with immediately one room to the left and one to the right, then down the hallway a little bit are paths going left and right straight into walls that move to reveal switches, and at the end of that hallway is a giant skull with a gate blocking the mouth. Normally you hit the two switches hidden in the walls and the gate opens. Okay, so if you know the exact room im talking about I can explain it now. As soon as you enter that room/area from the "altar room" door, looking straight down the hallway, go into the small room on the right. Defeat the enemy in there then look on the wall that is on the same side of the map as the door you came in from. From the doorway into this small room it'll be the wall on your right. There is obviously a secret door smacked in the middle of that wall, but it never opens. I've tried so many different things, nothing... Now you know the unactivatable Teleportor on Namers Island? I am CONVINCED that door goes to a room with the linking Teleportor from Namers to allow you to return to Chaos Island, because once you leave you can never go back in a normal playthrough. Actually, funnily enough there is an old forum online from the early 2000's where 1 singular human being on this planet talks about having gotten this exact door open and claims that a teleportor room is exactly what it was, and was wondering if anyone knew about it because he only ever got it open in 1 playthrough out of many. Thank you for taking the time to read all of this, sorry again it's rather long. This is just something that's been driving me absolutely crazy ever since my very first playthrough. Like what if you miss the Scroll or Staff (can't remember which one was on the island) of Wall of Bones? Surely the developers would've wanted a way for you to return. The whole thing's an interesting mystery that doesn't seem to get any attention, and I just would love for someone to use some walk-through-wall codes or some sort of map-warp hacks to finally solve it.
