If you falling down from the building, smash the "Start-Button", so it's all in slow motion and you can easier collect all the coins and crystals. - Your way is from MIDDLE to RIGHT, from RIGHT to LEFT, from LEFT to MIDDLE (the trickiest part i think), from MIDDLE to the LEFT. - If you miss a coin or a crystal exit the game in your pause-menu, go to the Story Mode, choose the Stage with the "Shinjuku Building" and try it again from the beginning of the Stage.
