Basic rule of any maze... Keep your hand on one wall and always keep that hand in contact with the wall. If there is an unconnected loop around the maze this becomes apparent quickly, simply switch hands to the inner wall. This works for almost any maze.
For finding your way through the fog. Enable description of sounds. When they are described they will clearly mark which side of the screen they are coming from. Then stop and wait after every movement to see where the sound appears next. Remember to follow a single sound until the screen changes, then follow the next sound.
