OpenOMORI: rehosting OMORI's desktop runtime in the browser

OpenOMORI rehosts the user's OMORI copy in a browser by replacing the game's NW.js and Node desktop APIs with browser-facing shims. It adds in-memory data decryption, a mod loader, map and event compiler, checkpoints and research-based story-route tools. The author reports coverage of early game flows on one Steam build in Windows Chrome, with later gameplay still unexplored.
