Tips, tricks & notes:

• Be sure to rotate the mirror back to it's original place before leaving the Death Ruins to allow yourself re-entry.
• If you forget to rotate the mirror back, you can get back to the Death Ruins through the Abyss.
• On the platforms maze, it is possible (albeit incredibly difficult) to get through without taking any damage if you time your movements and jumps correctly; try to minimize damage by doing this.
• You can free the Gnome you agreed to rescue by talking to the Head Mourner after solving the puzzle in the Temple of Light. This does not give any reward, however.
