Reader poll: Lunar Gravity

First of all, let me say that I've had Lunar Gravity looked at by several very skilled critics and reviewers. The general consensus is that it needs work badly. Now, if you're reading this you've probably favorited the story so you probably already like it, but I've come to a decision:

It needs rewriting. It deserves a coherent narrative and a decent arc because the story it's turning into isn't the one that's advertised and it needs a good error-checking. The question I put to you is this: what should I preserve from the current version? The character interaction seems to be the most well-received part of this tale, so that's in, but is there anything else that deserves to be carried over into the reincarnation?
