I'm watching my own Eclipse | The Building 71 Incident
The Building 71 Incident has to do with some kind of lunar cult in Brazil. I don't know if it's based on any kind of true story or anything, but I'm sure you'll find information on it if you wanted to look it up.
This game has been out for a while, but you can find it on itch.io:
