I liked the fights which are wisely settled.
The use of teleporters instead of stairs.
A good dungeon, not too tough and well balanced. Puzzles are simple but entertaining, some parts are pretty similar to the original but different enough to be interesting. With a little more furnitures and maybe more choice in the avalaible characters (The Daar prison happens too late in the dungeon), the gameplay could be improved, IMHO.
This dungeon is a little shorter than DM and is quite enjoyable.
