As I started reading this, I was like "This has ARG written all over it." And at the bottom: "The game developer said that it was his first ARG".
Looks creepy! Kind of reminds me a little bit of Funcom's The Black Watchmen. I was never quite brave enough to dive into that one, as I do believe they *call* you.
Did you play this fully? Would love a review. Was it more spoopy cathartic, or spoopy thrilling?
