Have left me with this review deliberately time because I wanted to test the game through its paces. Am currently at 119% and still have a lot of fun. And what can I say? .... It is used to great. Ingenious level design, crisp difficulty, good extent, fantastic music (thank you David Wise). Even my fear that level could consist of a too large extent of ice levels, could not be confirmed. It's made really great how each world takes its own theme. (Alps, water, desert) I am absolutely thrilled and can any fan of the series, as well as any still skeptical only wholeheartedly recommend this game for. Since the reason to buy the Wii U!
