Use this guide that I use it tells you how to do the paths and everything, but I don't think its accurate I'm starting to think more and more that this game is modified because I've found items in places where their are none and the guide doesn't even mention them. And their are inconsistencies with how you move the boulders in the ice cavern as well so that part is a bit difficult. But this guide will help you for the most part just use the J and L keys and K to repeat where the items are after you move through the paths, the guide will take you to most of them though.
