Mario Maker initially looked like it used the Nintendo Web Framework engine, there were similarities with Mario vs. Donkey Kong. But as time went on and they showed more, it developed into something I don't think the NWF can pull off. Not sure if they switched during the development when they saw the game showed progress, but as a NWF it should have been easily made. Even Mario vs. Donkey Kong which was a NWF game is being released next year.
