Well, let's start with some facts. At the moment there are 872'928 games on itch.io and 45'683 are tagged "horror". This is your competition on itch.io; did you have a look at them? The name "Suitor" (title of your game) is already present 8 times ! (all non horror games). Now to subjective opinions: your trailer didn't scare me in the least (and I scare very easy). You promise "A horror experience truly unlike any other" and then show a cute cartoony beast that does nothing special, only chasing me. Your screenshots tell me nothing and are like every 8/15 screenshot in a "alone in a dark house" game. In what is your game different from a normal chase /flee from an enemy game? What is special in your game that differentiates it from other horror games? From your game page I cannot guess. Another point: the appearance of your monster is not scary, so don't show it or change it. What we fear most is the unknown and everyone has a special monster-image in mind: showing the monster is always dangerous, so, if you have to, show it as late in the game as possible, not in the trailer. It is possible that your game is indeed a indie-horror pearl, but your game page doesn't entice me to play your game. Hawkzombie is a youtuber that plays and comments indie horror games: have a look at his videos, there is a lot to learn there! https://www.youtube.com/@HawkZombie 

I don't have a social media following anywhere

I've made posts on Facebook, Instagram and Twitter

Do you see the contradiction? You need to be already known to leverage your followers.

If we assume accuracy in ranking (it is not accurate), you are on place 22 of 38 in this list. What are places 23-38 doing wronger than you? What are places 1-21 doing less wrong than you? (Note: I do not know any game from that list. This might be, because I have different opinions about those tags - they are somewhat redundant - and mostly because I do not seek out horror in general)

Concerning your yt video. Look at the numbers of your gameplay video vs the numbers of your release trailer. This is small numbers, but I see a trend. People do not like to watch trailers for stuff they did not wait for. It is advertisement. Why watch yt advertisement to watch yet another advertisement. But people like let's play videos.

Concerning your game page. Could be better. Longer mostly. Screenshots are quite bland. It is a horror game. The shots add nothing to that information. Why is there no alibi story about a genetic mutated aligator in a science laboratory or whatever excuse. People like stories and settings. There is no motivation. An unknown person runs away from a green human raptor thingy or whatever. Why. Where. Is there a goal? Your advertisement is like for an arcade game, you only stress the dexterity aspect of the game and some supposed uniqueness. The mystery setting might have worked for Slender Man, as such games were rare and new. But as was stated before, there are just so many "horror" games. 

The description and screenshots of your other game is better. But you could tag more interesting tags, instead of the generic overused ones. Also, everythign here is indie, I think it funny that you and 20k other games bother to tag it.

While things in this thread might sound harsh, the truth is, that of that near million indie games on itch and you could play one horror game each day for years and not scratch the surface. You could do everything right and still drown in obscurity in all the other games that try to do what you do.

And this might be a translation thing, but suitor has a quite overwhelming non horror meanings. Is the monster courting the player, or asking to sign a petition? ;-)

suitor /soo͞′tər/

noun

A man who is courting a woman.

A person who makes a petition or request.

A person who sues in court; a plaintiff; a petitioner.

Oh, a podcaster exploring strange things and getting more than bargained for.

He could try to snap some photos of the monster for bonus points ;-)
