A clean update route for Windows
- Return to the main menu and export the current player profile.
- Store that export outside the game folder and add the release and date to its filename.
- Compare the version number on the project download page with the file you plan to use.
- Extract the new archive into a new versioned folder instead of merging it over an older build.
- Launch, inspect progress, complete a short level, close, and relaunch.
- Keep the prior working folder until the new build creates a fresh export.

Web progress can depend on browser origin and site storage. Export before clearing site data, changing hostnames, replacing a Docker container, or moving to another device.
The project explicitly warns that its website package and QQ group or Chinese netdisk packages use different packaging. Treat any switch between them as a migration, not a normal in-place update.
