Since Super Mario Maker launched last month, and many on the Wii U has been creating what they see as the "hardest level."

Nintendo's Producer Takashi Tezuka shares his thoughts on the user-created levels, and their limit in creating "extremely difficult courses" as "only a fairly small part of the whole game." He continued to say that Super Mario Maker was made to give people a platform to make "a lot of difficult courses."

"When you design levels for a product, you need to take into consideration a wide range of users, this limits the amount of extremely difficult courses to only a fairly small part of the whole game. I expected that the users who wanted to play more of the hard courses would be attracted to Super Mario Maker, so it’s not surprising to see that a lot of difficult courses are being made."

"There is a tendency for the courses people make to be a little harder than they think they are, the creator already knows the design, where they have placed their traps, and the best route to take. So it would generally be easier for them to play through than someone trying it for the first time. As a result, the course ends up being more difficult than the creator meant it to be."

Tezuka pointed out the fact that these levels is "a huge motivation for us developers to do better."

"I’ve been watching lots of different courses on YouTube, it was quite a surprise how much fun it was to watch the videos, without even playing myself. There are so many intriguing and inventive courses, like one which you couldn’t beat if you picked up a mushroom. It’s been a huge motivation for us developers to do better."

After only one week of launch, Super Mario Maker had over 1 Million user-created levels.
