@grizeldi As for actually constructive answer - I think the best option is to push it to some (smaller) content creator who plays this genre.
Because - how do you discover new games? You might follow a news source, a podcast, or a content creator who has similar taste to you.
If I want to discover a new survival horror game, I'll go to Avalanche Reviews or The Sphere Hunter. For brainy indie games, I have Triple Click. For JRPGs, Ircha Gaming.
Therefore, as much as it probably sucks because it doesn't depend solely on you, finding a small content creator streaming your niche and giving them your game for free in exchange for coverage is probably your best bet.
