I loved it, pretty good game. It's very frustrating at times with the barrel and cart sequences but there are tons of really fun levels. The graphics are superb, absolutely top-notch, tons to do with extra levels not found on the Wii version, unlocked once you've beat the main story. The boss battles are more varied than the recent 2D Mario games, loads of interesting enemies to fight. One of the best 3DS games, hands down.
