Super Mario Maker - or should that be the player creators - are showing their goods in the recent E3 demo of the game.
Giving you the tools to build your own Mario levels using objects from a handful of Mario titles, each with their own look and feel, as well as sharing those creations with others (and letting you download and play theirs), we're already starting to see some inventive level designs appear. You can check out us trying to finish just some (and tinkering with the level creator) in the lengthy gameplay video below.
