I'm glad you enjoyed it! This was my first real attempt at making a 'gimmick dungeon' and it is certainly rough (or at least not as intricate) as things I experiment with now. I should give it some polish down the line, or at least better put together a map for use at the table (as yes, those were meant to be cave squeezes, hard for the Wyrm to get through but fun to visualize in a very Dragonslayer kind of way!)
I honestly ought to give it that polish sooner rather than later, because working on this for Rakehell originally kind of got me on this whole other wavelength with regards to design thinking. Usually when I run sessions, my players don't enjoy dungeoneering. It is often too eclectic, with a lot of various rulings to adapt to (versus field rulings); so Maw of the Mountain as well as Bandit's Manse were me trying to put together one-shots that focused primarily on a single mechanism of play (loot tables, dungeon turns, etc.) It was a good place for my mind to be while designing it, tighter focus but things will get lost along the wayside. I'm more than happy that something from six or so years ago is a 7/10 and an enjoyable time which you'd use again.
All the best,
