Looking at a 100% save of NsmbU makes it seem so daunting, though I applaud your achievement!

You 100% in New Super Mario Bros U in ALL SAVES!? I 100% in just one save! (on my nintendo switch, soo... I can't prove this)

@Aquatic i only did it on one save! i just copied it to the other two slots so i could more freely mess around / try new challenges without messing up my save
