I may have explained the layout poorly.<br/><br/>The intent is that the intersection was where 3 different hallways met (the one they were in, one going left/right, and one going up/down).  Gravity has shifted so that is all turned around, but (if they can be reached with the weird gravity) there are still 6 directions to go.  The one they came from, the one the sound is coming from, and four others.  There is also the pit with water, but that is kind of off a hallway and not taking up a direction in and of itself.
