You can't beat the weird vibe of this module. Flopping, vampiric vermin. Dancing, hypnagogic horrors. Potions the party knows it shouldn't drink, but inevitably will.
There are a couple cool items. I appreciate the seeding of some spells for DCC judges who like their wizards to have to quest for them. Lots of unique monsters and hazards is very much in the spirit of DCC and is a great plus in my book.
There are a couple things that kept me from rating this a solid 5, however:
One of the most important monster's info is a bit spread out, and over two pages at that. This makes it harder to pick up and play. You'll have to study all the monster abilities and probably take notes to figure out how to run the encounter smoothly. Some kind of summary box or shorthand would have been appreciated.
Most of the room description text is short, but it runs long in a couple places. People will have different feels about boxed text, but my preference is two lines or less.
The map is rather sterile. It would have been nice if it had a few illustrations between the rooms for traps and monsters as reminders. One of the biggest rooms has bones littered about it, but that isn't conveyed on the map at all; you have to read a long boxed text to remember to convey that part to the players. The room title helps, though.
[4 of 5 Stars!]
