Curses (1993)

What starts as an attic search expands into a family home with routes into much stranger territory. Separate clusters joined by labelled links work better than trying to fit every discovery onto one plausible floor plan. The original final Release 16 gives you a clear classic version to map; reconstructed and enhanced builds also exist. This is an exacting old-style puzzle adventure, with concealed possibilities and ways to make later progress impossible, so keep more than one save.
