I got to the lever at the bottom of the farthest and tallest pillar in the back left. When I pull it, that pillar raises up higher revealing that thing I can't get. I have a time limit on getting back up to the pillar and get whatever it is that is in that hole that rises up. What is the fastest way to get up there? I can't swim fast enough. IF I'm even going the right way. Please help...I can't afford to break another controller!!
