×reach either the yellow door area or get beyond the creaky bridge. I managed to get here with a warp token and that doesn't seem to work. Tried (I think) using it on every square and nothing. Unless I'm not using the warp token correctly. Admittedly I don't understand how it works is it random??? Anyways I can't think of any other item that could allow you to get through any of that. Except the wall-walker getting past the bridge? which I think I also tried and didn't work...
