Lots of the puzzles, like B6 / B8 / B9, are much more fun with the new right-click. Feels more like a pencil puzzle, with less trial-and-error. And better than Taiji's sparkly middle-click.
But some puzzles, like B7, seem to still need trial-and-error, which is disappointing. Is there a way to solve that one logically? (In fairness, B7 is pretty small.)
I'm stopping at D9 for now, that one seems very tough.
