I'm really impressed with this and am eagerly awaiting each subsequent release. Well-structured, no busywork, well written and edited, choices have satisfying and extensive payoff, and lots of variation to be explored, and a turnaround time on new versions that is bordering on unbelievable. Well done OP, you've done in a couple of months what a lot of people here don't manage in several years. I saw this shortly after the initial release and assumed that like most things on this site, I'd watch it and come back in 6 months to see if there was any development, but on the contrary, the progress you've made already is incredibly impressive.
If I had to find one nitpick, it'd be that for some reason sugarcube/twine is exporting your code as a pretty much single line, which is an absolute nightmare to try to parse manually
