Nintendo Co. this week demonstrated Mario Maker for the Wii U at the Electronic Entertainment Expo in Los Angeles, CA.
The title allows users to create custom Mario levels, including classic 8-bit Super Mario Bros. levels and New Super Mario Bros. U levels.
Additional options include stationary placement of Koopas on specific blocks and the option to place enemies to respawn out of pipes.
At any point in Edit Mode, users can play test the customized level or switch back to edit. In addition, users can switch between classic Super Mario Bros. NES graphics or new Super Mario Bros. U graphics with no load times.
Mario Maker will be sold in 2015.
