If you are encountering a "Proper Paper" error or a specific site by that name, it may be a translation of a Russian file-hosting service (e.g., related to "РФ" or "Файл"). Be cautious when downloading .zip or .rar files from unofficial mirrors to avoid malware.

While that specific version is older (recent versions like v0.67.9 are currently in circulation), you can typically find and manage these game files through official or community-vetted platforms:

: Downloaded zip files for this game usually contain a pre-installed version; you simply need to extract the folder and run the .exe file according to user guides.

: Development stats and historical player counts can be tracked via Steam Charts.

: The game is available for purchase and automatic updates on Steam and Humble Bundle .
