Hello. Yes marketing can be quite difficult. The idea is to find a core audience. I focused on old school and obscure stuff so I used that to spread my reach on online forums. It's been slow lately but I aimed to have links all over. Forums, discord, YouTube, Facebook and Reddit. Regardless of your audience type it takes time and patience. It's easy to sink in the ocean of the internet. Just aim for clickable links that will remain prominent. Streamers can help aswell. As for indie horror like the other user stated it's a very saturated market at the moment. It's quite difficult to stand out from the pack. There is a real trend for these games at the moment. Also a variety of content can help expand your horizons. I'm not expert at all and I have only basic skills but I far exceeded my original expectations on here in terms of followers and downloads. Good luck don't give up just roll with the waves and things will go up and down. Dont give in just chip away at it and build yourself up.
