• "Left-hand rule" and "right-hand rule" work well in these mazes. In your imagination, place your hand on the wall to your side (left or right, pick one and then stick with it) and walk forward. Make whatever turns are necessary to keep that hand on the wall. Eventually, you will explore the entire maze using this technique. To retrace your steps, do an "about face" and switch hands.
• You cannot go back through an entrance door. All doors are locked, but there are keyholes only in the exit doors.
• A compass is an unbelievably useful aid to navigation. Too bad you forgot to bring one.
• Use the "peer" (hollow arrow) buttons to look around at intersections without moving your feet. Actually spinning around just to see where you are is the easiest way to get lost, because you can forget which way you came.
• Sometimes turning in place doesn't change your view. You have actually turned, but your view in the new direction is coincidentally just the same as the view in the old direction. If you think this has happened to you, just be very careful in deciding which way you should be going. This note is just to warn you that it can happen.
• Charcoal can be used to write on the walls. If you develop a good maze-exploration system using charcoal, write me a note and tell me what it is.
