First on the top floor BEFORE that one you need strangth to knock all the boulders down (That are moveable with strength). Then you go to the bottom floor again and go slide on the ice and if you do it right one of the boulders you knock through the hole will be there to help you get up there. OR you could use an Action replay code to fly anywhere..
