Interesting mod - I had first thought this was heavy RP, however it was more a Dungeon Crawl. What is excellent about this mod is the extra optional or replacement encounters. This allows for excellent replayability. I do think the linear map though could have used multiple routes or extra passageways.
The different environments and room layouts give some interesting play styles for monsters. As a DM, make sure you read ahead to understand how it will play out. I do recommend planning which encounters you'll use well in advance, so you can plan your battles (rather than choosing on the fly).
I would have liked more lore about the first room (and hints or puzzles with the statue). It was a little jarring for the players in trying to figure out what they were meant to do.
