I’ve sorted this walkthrough by levels, and then the images are just in order of puzzles. They’re full-sized, so I didn’t host them on this page (since they would stretch way over the edge of the screen.) If you see a pink arrow, that means that the level’s goal is behind an object, and the arrow is pointing at it.
This should have EVERY SINGLE ITEM asked for in the game, so it’s a complete walkthrough. Go ahead and pass it around, just don’t “borrow” the images, so to speak. I only have so much bandwidth. ;)
BTW, these of course contain MAJOR spoilers. So only click on the level you’re truly stuck on!
