(With reference to this post here.)
Sure, with the caveat that I'm not going to specify which of the cited metanarative horror tropes appear in each example – that would be spoiling things, after all. I'm also going to skip anything super widely reviewed and focus on the more obscure stuff, so no giving me a hard time for leaving out Doki Doki Literature Club. =P
Discover My Body is at the top of this list for alphabetical reasons, but it's also a great one to kick things off with. It's a narrative point and click game where you play as a medical intern observing a volunteer as their body is slowly consumed by a fungus. Packs an amazing quantity of body horror into a very short playing time. Free to play.
eversion is one of those games where everything looks cheerful and then surprise it's really a horror game. Sort of a precision puzzle-platformer, though light on the "precision" and heavy on the "puzzle" – most of the challenge comes down to routing, not execution.
The Fall is a point-and-click adventure game masquerading as a light metroidvania, in which you play as the onboard AI of suit of powered armour, tasked with getting your incapacitated pilot to safety. At the time of this posting, it's 80% off for the next 12 hours thanks to the Steam Hallowe'en sale.
Lily's Well is, I'm going to warn you right up front, one of those "awful shit happens to a cute little girl" games. It's handled in a mostly text-based, fate-to-black fashion, though, without any of the leering that often characterises the genre. It's about a girl who's been left alone and told not to leave the house; she, of course, does not listen.
NaissanceE is a first-person exploration title of the "you wake up in some alien ruins and need to find your way out" variety. Mostly a walking sim with some puzzle elements. Free to play.
Ossuary is a surreal quasi-RPG set in purgatory, in which the gameplay is built around inventory puzzles based on gathering and equipping various sins (which are apparently physical objects). Nonlinear and kind of obtuse – don't be afraid to consult a guide.
Perfect Vermin is a gory, low-bit first person action game where you're tasked with identifying shapeshifting monsters that impersonate furniture and killing them with a sledgehammer. If the aesthetic of this one grabs you, you should also check out the developer's prior title, Swallow the Sea; both are free to play.
Please, Don't Touch Anything is sort of pushing the definition of "horror game", but my post, my rules. As the title suggests, it's a locked-room exploration game where you're presented with a mysterious control panel and sternly advised not to touch it.
Stray Cat Crossing is what you might get if you took one of those super-artsy psychological horror JRPGs and took out all the combat, leaving only the exploration and puzzle-solving elements. Content warnings for child injury (including eye trauma) and death.
The Swapper is a twin-stick puzzle game whose central mechanic involves the use of a gun which can create copies of yourself and "swap" your consciousness among them. In spite of the visuals, the horror is almost entirely psychological rather than visceral.
They Breathe is a linear survival game about a frog exploring a flooded forest. Short, minimalist, and unreasonably effective at communicating a narrative with no narration whatsoever.
We Know the Devil is a branching-path visual novel about a trio of kids at a Christian summer camp being forced to participate in a bizarre ritual where they're left alone in a cabin overnight to confront the Devil. Strong themes of religious abuse, in case that wasn't clear!
(Widely reviewed games that I considered but ultimately left off in order to avoid loading down the list with stuff you've likely already heard of include Axiom Verge, the aforementioned Doki Doki Literature Club, INSIDE, Omori, OneShot, Oxenfree, Return of the Obra Dinn, and Yume Nikki. If I've guessed wrong and any of these have escaped your radar, definitely check them out as well.)
EDIT: As a reminder for everyone trying to add their own recs, if you include off-site links in a reblog, Tumblr automatically hides it from the notes pane and nobody but you can see it. Drop those titles without links if you want your recs to be seen by anyone who isn't you or me!
