The Umoria site hosts a WebAssembly build of this 1983 dungeon game. Browser saves use IndexedDB and remain in the browser profile where you play; they do not automatically move to another browser. Denny Games does not host the build or store those saves.
Denny Games has not verified this external build's gameplay, browser compatibility, controls or save behavior. Check the host's current requirements.
Play style: Directions. This game runs on an independent host or browser build. Denny Games does not manage its account, session or saves; see the notes above for how this build handles them.
