Wow. Really liked the ending. It was... different, and I can honestly say I did not expect it.
Anyway, what exactly is the function of the.Paradox Scope? I got that having it activated changes stuff, but it was kind of cryptic about it
Go back to key points in the story, and turn it on before you fight/try boss fights which were previously supposed to be "unwinnable". You'll unlock Paradox Endings that way.
