Social media is very powerful. However, this game is Christian, and I'm not sure how much longer that Christians will be tolerated on social media. For now it's a great idea.
I'm pretty sure that Steam would let the game on. I think a more stable, bugs-fixed release there would be better, so we should wait a while for that one.
Streamers (except for Christian ones) would not be interested in playing the game except to make fun of it, which would be terrible. Most of the popular streamers swear like heck anyways so that wouldn't be too great. But if there are some more lesser-known people who'd like to do videos of the game, I think that would attract at least some attention.
I personally discovered the game at the Museum of the Bible. So maybe a big Christian organization such as Answers in Genesis could support the game. I think if the game has solid biblical concepts (which to my knowledge it does) then they would be happy to help advertise or support the game.
