Current Demo patch status

The Steam listing offers a Demo, and Saikey provides patch information, but the saved product-page capture is incomplete. The available record does not identify a current Demo patch file, version, or compatibility range.

Treat the Linux guide as historical context

A Steam Community post describes extracting a Demo Reconstruction Patch v1.0 with innoextract and copying files into the Demo folder. It is a user-authored, version-specific report, not proof that those steps apply to today's Demo or a current publisher package.
