Then did John uuuh jumps off? He says he doesn't remember anyone. Maybe he isn't affected by the curse or he died before he could remember anyone, ending it?
I thought maybe Dvorak's Humoresques was haunted and anyone who listened to it dies. But that can't be true since John's listened to it as well. Not sure how else Dvorak Humoresques is related other than Amelia's playing it made Rupert remember her.
I'm still a bit unsatisfied without knowing all the answers but it was a good game and I'm glad I played it. When ACT 2 finally explained what was happening it was a big "ooooh" moment.
