At its E3 Digital Event, Nintendo confirmed the existence of the rumored game Mario Maker.

Nintendo's foray into the world of creation allows players to edit levels using assets found in the original Super Mario Bros. for NES. The trailer showcases rejiggering of the stages by removing the floor, flooding the area with flying Koopa Troopas, and raising/lowering pipes.

The trailer also showcases the ability to swap between the 8-bit art style of SMB, as well as the visual style of New Super Mario Bros. U. The visual user interface is reminiscent of Mario Paint for the SNES, even down to the cute flyswatter mechanics.

Mario Maker is set to launch in 2015.
