You really struggled a lot, but finally made a successful game! I'm really glad to see that. I hope the same happens to me one day. I'm currently working on a few horror games. My first one failed because it took too long to get indexed.
Anyway, congratulations! I truly understand how it feels to put so much effort into a horror game and then see it not gain popularity because of just one mistake.
This game is really good, you nailed it! It felt so immersive. I saw your previous horror games, they are also good but unpopular. Maybe, you could try doing some marketing on Youtube or other social media.
