It has the whole Portal Companion Cube idea where you have to use the Companion Cube to advance yourself - but you don't use a Companion Cube here. You use Mr. Saturn from the EarthBound series! I don't know if this idea has been thought of before, but if this is original then. . . I don't know! 
Go to https://pbs.twimg.com/media/CgNqwZcUAAAS_UI.jpg for a sneak-peak of the level before you download it.
You have permission to use this course in your episodes, like I will for Super Mario World 3: Back to the Island (an episode I'm making). You may edit it and re-upload it if you give a link to this article.
You have to launch the level in the Level Editor at the moment.

I hope you all enjoy! P.S. Try to record yourself beating it as fast as you can. . . it is a little difficult and I want to see you guys compete on it like a sport!
