This felt like a cross between "Simulacra" and "In Memoriam". I'm not a fan of Facebook, but it was nicely integrated into game. I particularly liked the gathering of information outside the game. But gathering the clues was fun in general.
I found the scope of the game decent. At some point it can get a bit tiring/boring to scroll through umpteen messages and you managed to avoid that. But I'm still looking forward to the updated version.
Fun game!
