It soon becomes obvious that you cannot always find the solution within the puzzles themselves. Given that fact, it's no spoiler that if the solution isn't contained within the puzzle, maybe you should look to things outside the puzzle (like your environment) for clues. I will agree that saying specifics beyond that might spoil the "aha" moment for some. Additionally, after playing through the game I felt the same way about it. Particularly the "post (meta?) game" puzzles. Perhaps some enjoyed solving those, but for me it was a tedious exercise that brought little satisfaction to the point that I ended up looking up most of them in walkthroughs.
