A browser-based roguelike synchronized with crypto block timing. A run is a race against the next block: reach the exit before the block lands, or the house wins. The same codebase runs the solo dungeon, the social Tavern, and operator-selected PvP and race rulesets, with separate free and paid leaderboards. Self-hostable under the MIT License. See README.md to run it, docs/ARCHITECTURE.md for the design, and docs/DEPLOY.md to operate an instance.
