I managed to solve all the puzzles that are shown initially (or at least I think). This walkthrough shows how to solve the first three, I'm not sure where to go from there but I'll still post it since no one else posted a video going this far. Hope it helps one of you figure it out! Edit: I figured it out and its really simple. View the rest for SPOILER
The numbers on the maze indicates the order of the turns you have to take.
