The true ending relies on collecting all trinkets. So lets get started filling out your collection.

Since the maze is really hard to visualize and describe I have thought of some stuff to make it as easy as possible:

• All directions are from the beginning of the maze.
  
• If there is a corner, it wont be listed in the directions, just follow the path.
  
• If there is a fork in the path, the directions will tell you which way to continue on.
