Lovely puzzle, found the midgame quite tricky but probably missed something. Very interesting logic, thanks!

Agree with TPP below: this is very neatly crafted and flows smoothly through the logic from beginning to end.

Having seen a couple of the drafts, this puzzle is the result of some excellent persistence in refining the logic to be as smooth as possible! Fantastic setting and impressively minimal grid!
