cool game with interesting mechanics! the only criticism i have is that the monster seems very out of place, and there's not a whole lot of reason behind why it's stalking you at your station. it's just kind of there.
My thought is that it's a demon that kills you for some sort of karma reason, like it only appears when all of the people in the house die, it also only appears when something bad happens in the house, so it probably knows the family and kills you when you dont successfully save the family.
