Hmm, I remember losing to her, but it was through sex rather than Hp loss. I remember healing as often as I could during the fight between waiting and shifting around to find the position that she doesn't smash my skull in.
Thanks for looking into it this much though, and sorry if it has been robbing your development time. Also, what is a save editor? (Joke, but I don't have one nor do I know how to use it.)
