Steam review snapshots
Video: Kavernum is essentially what I'd call a walking simulator, at night, in a cave.Anyway, the game takes about 30 minutes or so to finish and it's atmospheric horror where the most horrific things are what…Maybe there could have been more to discover/examine in terms of paintings/artefacts, seeing as it's an ancient location.Why it fits
Check it if you want adventure, simulation filtered by dark, tense, psychological themes.
