Aside from normal progression, there's a decent amount of memory log pickups you can find too, adding just enough sidetracking to give a bit more play time but not feel drawn out or intrusive. (cogconnected.com)
Playing it basically twice back - to - back (once for normal progression and a second time for speed trophies) made me realize how much of the game doesn't really take advantage of Rayman's many abilities unless you try and speedrun it, but even then, I felt like they could have done more.
