to me, sometimes, with some commentary, it might make it less boring, or at least much less scary to some people who feel scared to watch this kind of playthrough but still wanna go for it.
and well i dun get it tho. did that long haired girl show up to the short haired one only? and why did she want somebody else to help find her bro? many contemporary horror games feel like dat, leaving unexplained endings and scenes which confuse the players too much....
you are right but (just my guess) our friend wants to find her brother, but that's a lie because she want's to kill us. She is not a human, she is a demon in human form and try to bring us in abandoned place to kill us ^-^ but you are right! the end is always so confusing
