I mean seriously, how are they expecting anyone to find their way through those insane looping maze corridors and endless pitfalls?
The looping corridors are the worst thing about the whole dungeon, you will not only need to choose the right path in one fork, but in several forks in a row - and even those places have random pitfalls here and there which lead you to out-of-the-way areas.
Sure, drawing a map on a piece of squared paper definitely makes things easier, but it's hard even then.
