I like dungeon stories, but I've always felt they tend to jump straight into being an adventurer from the other direction. Straight into killing people for resources. It's really nice to see a new angle. That said, it's still very classically dungeon-y. Monsters, traps, the usual.
Still, there's a lot of potential here. Our Main Dungeon does want to seem to spice things up, and I'm hopeful as things develop the formula will get more of a shake-up, and we'll get even more puns.
