Just finished recently myself, had a great time! Writing was the right kind of goofy that tickled my funny. Might do some of the optional stuff I missed later, but not 100% sure. (Mostly because I think I hit all the major narrative stuff and the CGs.) Going to likely recommend this to someone who I think will like it.
I keep thinking of stuff to add to this comment after I post an edit but last thing, I think. Do you plan to do more in this setting? You did expand on the worldbuilding quite a bit, so there is room there.
