I think, the worst in this game is when you get a feeling that something is behind you, you turn around and you see it is! Somehow all your body jolts and you just wish to run and hide somewhere, but you can't hide anywhere since it's coming to get you no matter what.

I wish they made it somewhat more like Amnesia so that you can throw something at him or something to disable him for a second possibly or something.
I didn't really find it all too scary. At first I was a bit uneasy about being follow and the static shocked me at first, but then after the first time of being caught by the man I really wasn't scared anymore. The only reason I kept playing after the second time was because I really wanted to find out what happens when I got all 8 notes.

Whenever I got curious and ventured into a building I risked an extremely high chance of dying. Maybe a bit more puzzling to, because just walking and running around gets boring after some time. :P
