I finished it!
It's up and done!
All thirteen miniquests, 10 Sidequests, and three possible endbosses!
It all managed to get wrapped up neatly, and I'm satisfied with what I've got! It might get a bit grindy for my liking, but that's part of the concept.
Finishing things is satisfying! Now to wait for the inevitable glitches/oversights to show!
