Tap a post, fall through the screen, and talk your way out of a dungeon.
Built for Reddit's Games with a Hook hackathon. Play it two ways. Solo, you descend alone: type what you do in plain words and the Warden, the voice of the dungeon itself, answers. Community, a whole subreddit steers one hero together: players propose moves in the comments, the community upvotes, and the top-voted comment becomes the party's action. Server-side dice decide, the Warden narrates. One shared pool of HP. Permadeath. The only way back to your feed is down, past the thing waiting at the bottom.
Everyone is the same character. Every turn is an election. And the world isn't canned — when the game is installed in a subreddit, an AI generates a bespoke campaign themed to that community: its own setting, its own named villain, its own recurring motifs, and a campaign map that ends at a final boss. r/coffee crawls a different dungeon than r/spaceporn.
- Two lanes, one dungeon. A solo run is private and immediate. A community run is asynchronous and shared: the party's class, ability scores, HP, embers, inventory, and conditions live in shared state, comments are proposed actions, and upvotes are the vote.
- The Warden. Google Gemini narrates outcomes and authors the world, but never decides the dice — the server rolls. Everything the AI returns is coerced to a strict schema before it touches game state, so the model can flavor the world but can't break it.
- Classes that play differently. A Fighter shrugs off one killing blow per run; a Rogue rerolls a failed action each floor; a Wizard curses a foe to ease a fight. Room affinities grant advantage or impose disadvantage on top.
- Real tabletop mechanics. Actions resolve as D&D-style ability checks against the SRD difficulty ladder. A class's strengths grant advantage; conditions like poisoned or frightened impose disadvantage; advantage and disadvantage cancel.
- A journey with an end. A themed campaign map moves the party node by node toward a named final boss. Defeat it to win the run.
