Yes. And the rest of it isn't missing. I've just removed everywhere you haven't been yet. Consider the tunnels to be longer and the rooms further apart, the folks at Myriador had to condense it all to fit on a single page. There is a door to the left of the arrow which may be hard to see. It just made more sense to have the arrow going that way than the other. The exclamation marks are because people kept asking for a map of a simple corridor with two doors in the same wall and an entrance at each end :P.
I've moved the map to the map thread. It makes more sense really.
Map updated :).
