It looks beautiful (I have it on Wii U), but I find the controls to be a bit of a let down. The run, punch system is slightly off IMO. It's easy to start a running punch animation which locks out your ability to jump. This has caused me some problems when platforming.
Also, to execute the helicopter spin, you have to press twice, I feel the option to press and hold ala Yoshi's float jump would have worked much better.
Still, a fun game, Wii U features are nice, I don't even know how they would translate to other consoles apart from Vita?
Have been playing co-op with my girlfriend and its been good fun, although it would have been nice to be able to remap the control buttons.
I just can't shake the feeling I'm playing a polished 'flash game'.
