Read the book or listen to the original radio show. That will help you understand the deliberate and pervasive sarcasm, non-sequiturs, and Pythonesque absurdism (the author actually knew & hung out with the Monty Python crew).
Don't make the mistake of thinking I don't understand the humor. I've read the books, all five of them, and the humor in them is great. I just don't really care for gating that humor behind the obtuse "puzzles" of this game. I don't have the patience for that, and having to follow a step-by-step walkthrough defeats most of the purpose of it being a game in the first place.
