Surprisingly I got really engaged with the 3DS version :-O The levels there don't look nearly as pretty as the ones on Wii U / PC, but they got their charm : they're longer and thus offer more challenge !

They both play pretty similarly, but the 3DS version has a very different level design philosophy. A lot more gimmick levels, and WAY longer stages in general.

Play the Wii U version. The 3DS version suckssss
