I didn't find out you could roll continuously until you hit a wall until until the game literally required it in the Vanishing Road. I just flat didn't know. It is very odd that the game never requires this move. I had already beaten all the Golden Koopas without it -- it most certainly would have come in handy to have had knowledge of it. I also didn't know about the move that let's you swim fast under water (if you don't have cappy or if you throw him first) with those big strokes until a Moon in Seaside Kingdom required it. It makes me wonder why the hell more Moons didn't require these advanced moves to be used? I am pleased that a lot of Moons actually required long-jumping and wall jumping. But from what I hear, some people who played the game for weeks still didn't know all the moves, which is ridiculous.
