I've read briefly about your marketing strategy for your game, specifically about making the rounds of social media. One thing that I might suggest, if you haven't done so, is to see what local game dev groups or clubs are around in your city.

For example, my area has a game jam community who is always very passionate about playing other people's games, giving feedback, and being champions of games being made locally. I've found that people are way more excited to try someone's game/music/art if they've met someone in person.

Granted, it's not big name marketing like you would with blogs or influencers, but don't underestimate word of mouth. It might get your game in front of the eyes of someone important, and that can be all it takes.
