The Last Door: Collector's Edition (2014)

A country house, school and city streets become unsettling through what you can no longer confidently explain about their occupants. Its sparse pixel art makes you interpret ordinary shapes and sounds before the investigation gives them a darker context. Choose the first season's Collector's Edition as the starting point; the larger mystery continues in Season 2. It is a reading-led Victorian horror adventure with practical item puzzles. The supernatural invention grows far beyond an initially recognisable social world.
