This was great fun to play, I loved the mystery of who this girl was. At first, thought the girl who left, then thought ex girlfriend? Then started to wander if I was responsible? I hope we get to see more and maybe more explored.
This had some really eerie moments, and I loved that it happened in like a couple of days too. Not bad!
