No official walkthrough, I posted those tips in a stickied thread, but if you tell me your items/things you haven't made use of, I'd be happy to help.
well the things i havent used is the hammer the rest i need to find but i gotta admit its a nice puzzle but sat for 3 hours trying to figure out where the hammer is useful and the rest i need to find like the thing for that panel with a green and red button where you need to remove that thing if that makes sense
