I'm late to the party, yes, I know, but I've just started playing Ubisoft's Rayman Legends. I'm working with the Sony PlayStation 4 version since that's what GameFly sent me as a rental despite the game's Nintendo Wii U origins. The exact platform is irrelevant today though because each version includes this awesome level I'm showcasing. It's Castle Rock, one of the stages that times the background music and foreground action together. Play the level correctly and all of the action syncs up. I love when this kind of thing happens in games by accident (see my playthrough of the Throwback Galaxy from Super Mario Galaxy 2, for example), so of course I had to show off this stage which deliberately invokes the gimmick.
