Either the map or the area descriptions should have been more specific about where exactly the traps were or where the NPCs would stand. I had to wing it and guess.
For low levels, even after adjusting for the very weak party rules, the early and late encounters can be brutal.
Overall, little preparation is needed.
I enjoyed the small amounts of humor, especially the self-pit puddy.
The limited roleplaying was a good start for my mostly under 15-year old table.
