Highly recommend! Recently finished a play-by-post game, converted to Cairn 2e system.
As a GM, I found it a really interesting small dungeon setting with several equally interesting hooks – lots of flexibility to fit into our campaign and space for GM creativity
There's good texture to the dungeon: not every room poses a threat so players can rest and tension can build. It can be as deadly or as mysterious as you want to make it. Multiple pathways to explore the entire dungeon. The monsters are interesting and deadly. There are a few weird little NPCs for players to interact with. There are a few small riddle/puzzles (which the players solved way faster than I expected).
The artwork and zine design are top notch!
