I personally think this game could have had so much more on to it. perhaps it was rushed in time for launch or something... I was actually one of those people who was really excited for this, but I sometimes struggle to find the will to play it. The reasons for my disappointment is that the levels didn't seem innovative at all. There were no unique unlockables either like.. i dunno - maybe DAISY as a secret character. THAT WOULD BE BRILLIANT. So in other words, there was nothing special about this game for me.
The good points which i love nintendo for is the difficulty! I die a lot - teehee~
I also am loving the new world map, but it's still not enough in my opinion for any kind of award
