A fun dungeon crawl blending sci-fi into fantasy, a la Expedition to the Barrier Peaks. I particularly liked the 'magic' item design - who can say no to something called a 'Lend-a-Tail'? The art and cover is really evocative.
I really like how you re-presented the map inline with the room descriptions, but I feel like I'd still be flipping back to the complete map pretty frequently - perhaps it could be moved until after the descriptions of the inhabitants of the cave, so that it's right next to the room descriptions? I'd also consider moving the tags for room features to the beginning of the line, so they don't get lost in the text.
