As a fan of the 3d Mario games, this entry is one of most fun so far... everything just feels right. The environments look great, Suwa is perfectly stylized, the music fits; but most importantly, the platforming is good where it counts, with really smooth controls and movement mechanics.
The adjustable difficulty of picking up as many coins as you want (or can) for a high combo on beating the level, combined with the timer bonuses of jumping and diving properly flows really well. On the second level, it was really satisfying to sail around the platforms when I landed the right timing and coin path. Although there were times that it felt a little tedious to mess up a combo and start over, I blame that on my own sense of perfectionism.
