The 3D is definitely put to good use in this one. I've really enjoyed it as well and I'm still logging hours with it on my 3DS. Now that you mention Return to Dream Land, I think I may have to give it another shot. For some reason I really wasn't enjoying that one, so I bailed on it after a few levels. Might've just been the wrong game to play at the time. If it's anything like this, I'm certain I judged it prematurely.
