After the part where Naniko has to pick off the snipers, turn the wheel and throw a guard into the gong before the two walls close that on each side of the gong, what do I do after that part is done and Naniko goes into the tropical stage, on like a sort of bolder rocky bridge part, which is sorrounded by tropical trees, cloudy background and very light rain falling? There is apparenting a invisible wall, where Naniko cant walk straight through it. She cant turn back as the wall has closed. There is no help to even explain what to do on this stage. Help!!
