First turn the switch toward the pathway to the Hourglass room. Now go back
to the "eye" and face towards the path to the Hourglass room. You should now
be able to see the eye, the switch and the path to the Hourglass room (in that
order). Drop down to a slightly lower ledge. Now hang off the side of the
ledge that is pointing towards the Hourglass Room (wow, important room huh?).
Now jump towards the wall and keep wall jumping until your reach the bottom.
Drop down on to the lower ledge to the left.

"I am stuck. I can't figure out what ledge to wall jump from. I climbed up a ledge, and dropped down three ledges, but when I attempt to wall jump down I just die. Is there anyone out there who has this game, and can assist me? Thanks.
