Blackness

"Blackness" happens when the camera enters an area where it renders nothing. It occurs at the north and south ends of every level.

Note that the Companion Pointer is processed separately, so it will still show, despite else everything seemingly going dark.

Tips

 * If you want to find where the edge of the blackness is without getting lost in it, try pointing the camera away from the edge of the level and walking toward it. This helps because the blackness is based on where the camera is located, instead of where the player is standing.
 * If you happen upon the blackness without trying, stop, and go back the way you came.
 * You can try rotating the camera around, since it might end up coming out of the blackness. But if it doesn't, then you'll probably lose any idea of which direction you came in from,
 * Playing with a friend can help; either the Companion Pointer can point the way out, or your friend can guide you.
