This is what i meant by my plan, if you'll ignore the outdated map.
Jump through the middle plate in the lever corridor just in case, then run, through the ones the creature raised, then jump into the middle patth corridor tile. After that, since it's not far from the wall (That is there's no distance) we can easily seal our shoe in the wall as a 'stepping stone', and we can scale it to the other side. If we need to, we can even use 'unseal' to get another step or two. Though i would only use it if necessary. Once we get in the corridor, it's easy, just go activate every single plate on the way until we go back south. Boom, we'll have done every single tile.
Since we haven't found any door anywhere, I must presume that ocne we take out all the tiles that's it.
