Nintendo is in the process of doing a Mario Maker world tour of sorts, inviting youtubers around the world to make levels, which Tezuka and other Nintendo developers will then play.
So you're given this honor. You get to make a level to be played by one of the co-creators of Nintendo's most classic games. What do you do?
Make the worst, most assholish troll level you possibly can, apparently.
Italian, where the first jump requires pinpoint accuracy to avoid death, and multiple places where you are required to take a hit as big Mario to proceed
Portuguese, complete with Kaizo block on the first jump and deathtrap doors
Tezuka gives these levels like 3 or 4 lives before he passes the controller on, and from what I can see Nintendo has to call in their star players just to complete them.
Poor Tezuka.
