Nice choices of art, am I right in thinking you drew the map? Because, that's great too.

I like the idea of how long players take impacting The Captain's condition when they find them, that really raises the stakes if you sell that to them from the beginning. The size references you used were perfect.

I love the tables on page 15, those are useful in and out of this adventure. The areas were well described, I especially liked 9. Feast Room - the anglerfish (Boglin) lurking beneath the surface would be quite ominous for players.

I liked all the Rival Adventurers and Hirelings personalities and a nice addition would be stat blocks for them, to save the GM a few steps.

Beautiful adventure! I'm a sucker for caves, and you really did them justice. I love the premise, your hirelings, and the mechanic for determining if the adventurers are too late.

Very easy to use dungeon crawl. I like the size descriptions for each room.

Well done. Real slick. Every detail I'd have to make up on the fly, you've got an answer for here. Balances psychological journey with dungeon well. Love the room size examples.

I felt like I was actually in that cave as I read. Great stuff!

Very claustrophobic adventure! That one section with the breath–holding squeeze – I could feel that in my bones. Really nice concept with a turn being ~2 hours: that's a nice break from the more traditional dungeon crawls of the osr.

The feel of claustrophobia in this is real. I loved reading this and have a strong desire to run a multi day spelunking adventure!
