I ran it with my Stewardesses group (in case you haven't heard, I DM stewardesses. You may bask in my glory) and we had a blast. I adapted it for the "Oriental" portion of my Barsoom campaign setting, took out the "Wrong Turn" and a couple of the encounters ( Shocker Lizards, Water Mephit, Harpies) and completed it in a breathless four hours.
Good fun. I've posted the first portion in the Stewardesses Story Hour, linked below, and hope to complete that tale eventually.
I'd LOVE an adventure set at Felicia's wedding (hint, hint).
General thoughts: it was a good, fun adventure with a straightforward story hook and a good variety of encounters. The chase mechanic I didn't use at all -- I just had Maliss show up whenever things got too quiet. He was a good, creepy villain and the adventure generally speaking did a good job of working with personalities and places. It's one of my favourite adventures of recent Dungeons -- up there with "Heart of the Iron God" and "Tammeraut's Fate".
As you can see, I like the DIFFERENT ones. But I would welcome more adventures like "Snake". Good work, John!
There was a memorable encounter on the underground river as our heroines are speeding towards the falls while Maliss lurks behind their rowboat, firing arrows out of the blackness -- quick thinking, a nifty use of far hand and a torch and Wei-Yong's skill with a bow saved the day.
