Leaping Backwards.I have only been playing this for a couple of days and am stuck. The walkthroughs are of no help here so I will have to ask the question myself, OK I am in the city of Vilcabamba I have got the artifact and other bits, but am now trying to open the doors. I have done the one on the right now am trying to do the one on the left, I can get around the pool easy, but when it comes to leaping back towards the platform to do the other bit I always fall short, why? Do you need to be in a certain place or what? Have I done something wrong? Any help would be greatly appreciated. P.S When doing Croft Manor Lara wont let me use the Grapple I keep getting told ''No'' in a posh voice. Many thanks.
