This is a very well made adventure for Cairn. The rooms, map, and stat blocks are very clear and the layout is very readable. The rooms feel like they have a nice variety of gameplay and everything feels like it belongs in this place.
The one thing I would maybe tweak if I were to run it is to move up the timeline a bit. Leaving the party 2 weeks to solve this would let them retreat and recover at least once. I would worry about that undercutting some of the challenge of this dungeon since it's not particularly long or especially deadly. But then again, OSR games can turn on a dime, so if things happen to go particularly bad, the recovery may be necessary for the players to even see most of the adventure. This is extremely minor. I wouldn't even call it a complaint, just something I would think about if I were to run it.
I really like this adventure guide. Its very clear where the points of interaction are, and there are plenty of them for players to discover. I also really like the goat image. It's very charming in a kind of roadside oddity kind of way.
