Couldn't resist checking out something described as a "Kafkaesque dungeon crawl"! I love the theme and I'm impressed by how much you're able to pack into such a tight space. I also really appreciate that it focuses more on the story of the dungeon and the party's traversal through it; of course, that's probably the better thing to focus on for a short jam.
Feels like a classic adventure that might have shown up in one of the old D&D magazines. My only complaint is that the red-and-white on black is a little hard to read...but maybe that's appropriate for the setting!
