I'm running my group of mostly kids through this. They are about 1/4 of the way through in 3 hours. I gave them a hook of one of the character's sisters being missing in the graveyard. I also told that player (the only other grownup in the group) that his character hated the town, and couldn't wait to leave, so we got some actual role playing in for a change. They got very distracted by a side-trek tomb, on the assumption that EVERY room has something of value to them. It took them about 15 minutes to complete the beholder puzzle, with no clues from me (but I did make a copy of the picture, and another so I could cut out the matching tiles - that helped).
I can't decide what to do with the maze, but I have so many FL maps, that I think I'll use one/two of them. I am letting them level up, as they aren't very experienced at the game. If things get too easy, I just let the monsters last a little longer.
