I'd absolutely be interested in more setting details, or a sample adventure, or stuff like that, and I'm super glad it's still being worked on.
A glossary for stuff like Punyal and Agimat would help me (I had to look them up,) but I also sort of like that they weren't defined and I had to look them up. I had to do the same when I first ran into stuff like flamberge or glaive in DnD, and it was an opportunity for me to learn.
Apart from maybe a sample adventure or spell list or short bestiary, the thing I'd most be interested in would be a paragraph of what a typical day is like for an average character in the setting. That might help a bunch with describing NPCs, towns, and the environment.
