Observed GitHub stars: 0; last pushed October 24, 2026. Selected below the popularity preference for a distinctive static browser-native puzzle absent from the live catalog.

SkillSafe edition changes:
- Native editable hash console for embedded browsers
- Guarded in-game history Rewind
- Keyboard editing focus isolation
- Accessible live room/results status
- Canvas layout reserves space for console
- Locally bundled assets; no runtime dependencies or network requests required

Upstream game engine, generated geometry, collision/plates, browser-history echo, key reveal/redaction, score and local progress retained. No remote assets, services, accounts, downloads or popups are needed. The upstream Vite/TypeScript tools are build-time only.

Play: arrows/A/D to move; edit x= or key= in the URL hash and Apply. Rewind is browser Back, leaving an echo at the remembered location. A fresh run generates new layouts. R replay / Escape menu after finish; buttons also available. Reload regenerates current room instead of restoring stale geometry.
