That was a huge twist. During normal mode, when you fight the boss, you are the boss and you kill the hero. That makes sense. When I got to the boss in hard mode, I was still the hero, so I thought, holy crap, will this be a different ending? So I fought the final boss for half an hour failing time after time, and when I won, it went to a cutscene of me getting killed... WHAT?! No alternate ending for hard mode? That sucks...
