I would focus more on the alien-worshiping cult part. "Eerie, lo-fi visuals" is just telling people that the game is scary. So is "adventure-horror experience," although that's excusable because it describes the genre of the game. It's better to show people a detail of the game that will get them intrigued and wondering what the game is like than to just tell them what the game is like.
Viewing post in Pitch your game: "One line to lure them all"!
I guess just an interesting fact about the game? Something about its story, or its mechanics, or anything really, as long as it's not obvious. So if I say my game is a puzzle platformer, that's pretty boring, but if I say it's about the struggles of a ghost trying to be an adult, that's a lot more interesting.
