Any recommendations about puzzle design books or readings? I´ve found that I am pretty bad at designing puzzles. My testers are always lost and very often they don´t even have a clue about what´s happening in my games. Sometimes I think I´ve designed an easy one only to find that it is nearly impossible. And then, I try adding hints to fix the problem and the puzzle becomes so diminished that maybe it isn´t a puzzle anymore.
Anyway, I am looking forward to plunging into some good analysis.
EDIT: I don’t feel like I talked this up enough. It’s probably the only thing I’ve seen or read that gets at the heart of what a puzzle is and why you would design one. It gave me a new way of looking at puzzles, which I think is pretty actionable, or at least will become a part of your thinking when you design a puzzle.
