Very nice! I had been wondering you constructed these. I've enjoyed playing them! A question I would have is how meta do you think can you get with these hints? In crosswords, you often see a lot of references to other clues in the crossword. And so I wonder, with bracket city puzzles, it seems like it would be hard to dip into that self reference, as the tree structure of the clues makes it hard to reference other clues and there's no labels like 2 across you could use.
