I had heard good things about
New and Improved, a puzzle in this year's Mystery Hunt, so I figured I might as well go solve it. I've had it open in a tab for something like three weeks now, after all.
I started listening, started taking notes, got to the end, and thought, "You know how this puzzle
should work?" It turned out that that's exactly how the puzzle did work. It's a great puzzle with a terrific concept (and I say that not having actually thought of it, because I only had the "it should work this way" thought after getting enough evidence that it even could work that way). Well done, person who I can't identify by name because they still haven't posted answers, but who I think I recall being Jangler!
(But seriously, it's been a month. How about answers?)
