At some point soon I may take you up on your offer. 
It’s probably way too soon to give this update because there’s still plenty of time for things to go wrong, but I started re-encoding the storyform with an OS of Psychology and everything seems to be coming together – from this vantage point the story suddenly seems darker, “twistier” and much, much cooler. And even with this big change I actually think I’ll be able to use most of the good stuff I’ve already written (and the new storyform allows me to jettison the stuff that felt “meh”).
This is all quite surprising to me, though I guess it shouldn’t be.
