The game is really cool, and it's clear that something special happened between the hero and the Queen—some kind of special bond and all that. But the Queen could have stopped the hero all this time; it would have been enough to break his arms and legs and leave him to suffer in agony, healing him just enough. It's the simplest way to deal with Heroes with restart abilities. But no, she let him die so he would improve and become stronger.
I know my comment is kind of a buzzkill in a way. But I feel sorry for the Queen. That little brat deserved to suffer.
