Aw, thank you! Glad you've been enjoying it, I'll keep at it. Characters are the real draw IMO, and my favorite part to write, it makes sense to try to double down.
I'd like to aim for an even 10k words a week honestly, would be a good goal at minimum to have ~4h of content a month, but I doubt it'd be completely sustainable.
Ultimately, new mechanics, areas, especially difficult scenes, etc. will doubtless slow it down, and lots of inspiration or early starts can speed it up. It's just a number.
