This is cool, I immediately did 4 puzzles in a row.
In addition to saying congratulations, I wanted to ask, since you say you're the one writing the puzzles: how do you define a puzzle? What does it look like from your perspective? Do you literally just write all the nested clues out with brackets and everything, and then validate that it works—because that would drive me nuts, I think—or is there some tool you wrote to help?
