Its driving me mad. Its for the ps3....! Thanks

k this happened to me to heh, during daytime go back to the main city, with the university, there you go to the level select area west from the university and you should see this big thing to bounce on to the right, where there's a small space where sonic can't slide because of a laser, like in the ice level entrance..you have to do that level first..and just stomp on it about three times..a lever should come down from the sky..yes like magic, and get on it and jump the wall, there's a pair of shoes there that will allow you to wall jump, then you go back to chun nan, there you go to the top of the narrow walls with rings and get his super bounce shoes and move on, need anymore help let me know ^^
