A lot of cool things going on here, and I'm excited to see what happens in the future. One comment, though not a request, is that the barebones and very sterile visual presentation on the UI front presents a significant barrier to immersion. The look is passable for a lot of other QSP projects, if still underwhelming, because they are set in modern times, but here it clashes hard with the theme of the setting.
I fully appreciate that UI, and the visual design for it, is a craft in and of itself, and having worked with visual/UX designers several times in the past, I know that they don't come cheap. Hell, I don't even know if custom backgrounds and window borders are within the scope of what is possible with QSP. So I am not throwing out some "omg you need to do this!!!!1" comment here. It's your thing and what you are making is compelling. But if you can find some way to improve the presentation beyond the HTML look, with things like theme fitting window borders and backgrounds, it might be worth considering.
