Legendary game creator Shigeru Miyamoto teams up with Retro Game Master/Game Center CX's Shinya Arino to tackle a fiendish Mario Maker stage and give us a sneak peek at the sort of custom, nightmare levels we can expect the Nintendo community to create once this baby hits the market.

Right off the bat, things are both familiar and different in this Mario Maker level (starting around the 2:13 mark in the video). Everything has the look and sound of the NES' original Super Mario Bros. game, but with some new twists. Cannons spew loads of coins to help players stock up on the extra lives they'll be needing, giant turtles pop out of item boxes, and there's an Inception of bouncing with a section of springs bouncing off of one another. It's absolute madness! It's so mad, in fact, that the creator of Mario himself can't even make it through the level, so he turns to the Retro Game Master himself, Shinya Arino, to get everyone's favorite mustachioed plumber to the finish line — which he does in style.

Fans of Kaizo Mario, a Mario Romhack so difficult it's sometimes called the Super Meat Boy of Super Mario Bros., will finally be able to inflict their mad creations on the general public with Mario Maker. This test level shown off by Miyamoto and company makes it clear that Mario Maker lets players get pretty wacky with the traditional Mushroom Kingdom formula. With hundreds of items to utilize and four distinct Mario styles (Super Mario Bros., Super Mario Bros. 3, Super Mario World, and New Super Mario Bros U) to choose from, players should be able to whip up the most awesome levels imaginable and then share them with the world.

Mario Maker is slated for a Sept. 2015 release on the Wii U.
