So I'm at the part where you have to jump along all the platforms while the giant water blob thing is trying to kill you and there's this part I've died at at least 20 times already. It's about 20/30 seconds after you press O to get Piers to pull Chris up... I notice Piers jumps over one of the platforms but Chris just crawls underneath it and then plummets to his death when water blob slaps him. Help? Anyone?
