Warning to everyone thinking of purchasing that 'guide' hoping it will help solve tricky puzzles - NO WAY! Just wait until your favorite gaming website posts the walkthrough and get all your questions answered for free. =))
That 'official guide' sold for $10 is just a manual that should be included in the package without extra charge. The most of that 'guide' is copypasted from in-game help, with useless (mostly random) additions. There are lots of 'puzzles' in the game that can't be solved using logoc or common sense, and this 'guide' solves NO ONE of them!
Well, I understand that LDW may want some extra cash because of that creezis-shmeezis thingy, but it's not the excuse to lie to the loyal customers. LDW has tons of loyal customers who will happily pay $25 or even $40 for their product (provided that it's quality product, not random junk), so there's definitely no need of this trickery.
