Well, that's it! I didn't find any more obvious bugs. Nice module!
If it was me I would add some more details, things to interact with. There are perhaps too many "strategically placed" dead bodies with healing potions
But don't let my sentiments stop you from publishing it! It will fit nicely and people who played the first chapter are anxious to play it.
I didn't run through every possible course of action. I don't have time just now. Good luck!
