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 would have liked a scroll bar while reading through old messages. But it works quite well as it is. I ran into a bug once: One of the endings only showed the picture, not the accompanying text. Unfortunately, I can't remember which one it was.
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!
