It's pretty annoying, but nothing that can't be overcome with rampant savestate abuse. (dreamandfriends.com)
I suppose it'd be ok to play on an emulator with savestates but I haven't done that. (nintendoworldreport.com)
But on the Wii U there is no way to play the game frame by frame and create savestates, so the most you can do is play back input that you recorded previously, and that input has to come from somewhere, i.e. yourself or somebody you know. (reddit.com)
