I just got to play it for a bit and so far it's excellent. Music is great, visuals are a lot better than the trailers I watched on the eShop. Very crisp and clean, plus the 3D looks amazing but doesn't add to the gameplay really. It's a mix of action/puzzle platformer. Neither seem to get really TOO complex but I'm still early in the levels too. The only thing I'm worried about is that the levels are very short and if the game doesn't have more than the levels featured on the level select screen, then this is an incredibly short game. It can probably be beaten in less than an hour.
