: Thanks. Never would've got that. My puzzle solving skills aren't exactly up
: to snuff...
Yeah, it's probably one of the puzzliest puzzles in M2, and it has always been one of my favourite levels, right from when I first watched my brother playing it. Even the first trick of going underwater and through a door, then swimming and coming out somewhere totally different was a great one - and even then the same sort of thing had me confused for rather a while on Thing What Kicks... in M? the first time around.
Unfortunately it's things like that that you then remember forever, somewhere up there. That's why I always think if I ever get amnesia, I have to play through Pathways Into Darkness and everything Marathon again :).
