Seems quite easy at first, but the level design gets more and more clever and soon you are hooked.
Sound: 9.0 The sound is great an really catchy, -1.0 for being somewhat repetitive as each different soundtrack shows up at least once in each new world
Graphics: 9.5 Great looking graphics for 3ds standards, good looking 3D that is not required, but can make some things easier when used in certain situations, -.5 for 3D not being used as much as it could
Control: 10 Great control as 3DS circle pad is very fluent, no complaints on this one
Replayability: 10 When has Mario ever not had high replayability? (Mario is missing, Mario's time machine) but this one gets no demerits, you can go back to get all the star coins, or just try to beat in fastest time, or once you beat the game you can replay it again with new different worlds and the ability to unlock Luigi
