E3 2014
Originally called Mario Maker, it was first presented at E3 2014 with a demo that the attendees could play with the following differences compared to the final game:
 * Ground Blocks had to be semi-solid ground is in the final game.
 * In the Super Mario Bros. style, objects had heavier shading, certain objects looked shinier (Coins, Question Blocks, and Brick Blocks), and the background had a grid pattern compared to the final's recreation of Super Mario Bros. background.   File:SMM_E3_2014.png
 * At the beginning of the course there wasn't a sign.
 * Coins emitted sparkles when collected.
 * Details that automatically pop up when your creating a course weren't in the game yet.
 * Enemies exploded when Mario touched the flagpole.
 * In the demo the timer was set to 999 unlike the final game which can only go up to 500 seconds.
 * Instead of the final game's square icon for selecting which way you want the moving platform to go it is instead circular.
 * Instead of the clock icon used in the final it instead said Time over the Time.
 * Trampolines in the Super Mario Bros style had a different sprite then the final.
 * Super Mushrooms could not be placed on their own in the demo and were instead in a block automatically.
 * The HUD in the editor looked completely different then in the final game.
 * In the Editor instead of the rocket ship it had a trash can and the Undodog and hand had their original sprite from Mario Paint.
 * There was also an button for placing objects with a hand representing it.
 * Weird Mario had a different sprite looking more like a stretched out Small Mario instead of having his own unique sprite.
 * In the New Super Mario Bros U theme the animations were different
 * The background was flat in the NSMBU theme and none of the objects (clouds, hills, etc.) didn't move along with you.
 * Whenever you finished a course in the demo a voice saying Congratulations could be heard, confetti would fall along with some Super Stars, and a few hands would clap for you. In the Super Mario Bros. style the hands were pixelated, while in the New Super Mario Bros. U style they were smoother.
