I'm incidentally realizing that the typical "horror" style is difficult to add a unique mechanical premise, and this was a lesson no better taught than one of my own projects that was unable to continue development. The speed of depletion for the lantern was a pressure wholly mitigated by the lengthy process of refilling it. I gathered the three key-cards of the stone-brick mansion and hastily concluded my dread.
The game is skeletal in terms of designing the typical tension of a Nerve game, but I find a fair amount of intrigue for the setting's blend of Victorian drama and science fiction. This juxtaposition could create events where the player needs to fill the door with oil as well as collect its card, whereupon they would be placed in an especially dreadful chase sequence.
Amnesia: The Dark Descent was mostly popularized for reasons beyond itself, but its similar blend of aesthetics along with its gritty, blurry health and stealth mechanics give a surreal atmosphere that's retroactively perfected in Pathologic, an even older and more niche title. What this aesthetic lacks to its benefit is a full-blown severity that would dour its fun moments when they manage to appear; this contrast is elevated in a second-hand medium, and perhaps what made for such captivating videos on Youtube.
