We Harvest Shadows is both a rustic PT and a first-person Stardew Valley

About 30 minutes into the demo for We Harvest Shadows a picture appeared on my wall, just by the farmhouse main entrance. The picture is of a long hallway of nested door frames, with a sealed door at the end. Any mystery it offers is, in theory, cancelled by the tutorials, which briskly informed me that the picture is, essentially, an alarm system. It will change in subtle and less subtle ways when danger is nearby. Still, this blunt advertisement of mechanical purpose does nothing to dispel the artefact's menace.
