I wouldn't call me a savant, and will admit I peeked in this thread for two specific things but each time it was just hints I looked for and not solutions.
I feel what helps with me being able to understand the puzzles and work through them quickly is actually my programming knowledge and ability to mentally visualize solutions to puzzles (particularly tetris ones). Many of the symbols can be thought of similarly to programming logic, particularly the upside down Y sign which I personally call a
(spoilers for those who don't know what it does).
In the end, the key is just to being able to visualize puzzles and work out the puzzle language that Blow was talking about. He wasn't being pretentious, there really IS a language to these symbols and coming to read what they mean and visualize the solution based solely off what the puzzle says... Not only can it speed things up considerably, but it's a revelation when it hits you. To clarify I don't mean the puzzles actually translate to letters or anything, I just mean the logic behind them, hence my programming language comparison. Wouldn't put it past Blow though for the panels to have some deeper meaning!
