If you're looking for horror games that tread lightly on jump scares while introducing unique mechanics, you might want to check out "Amnesia: The Dark Descent" if you haven't already. Its sanity system creates a constant atmosphere of dread without relying solely on cheap scares. The way darkness and light are used is particularly clever, forcing you to weigh the risks of exploring versus staying hidden.
Another title that's worth considering is "Soma." It combines philosophical storytelling with a sense of isolation that's deeply unsettling. The game's AI interactions and environmental storytelling pull you into the narrative without overwhelming you with frequent frights.
Also, keep an eye out for "The Invincible." The demo shows an intriguing mix of exploration and a sense of existential dread, which could provide a different but engaging approach to horror.
