SuperKamek's Super Mario Maker Courses! XD · 10:42pm Mar 20th, 2016
They are REALLY difficult, but also amusingly challenging. Here is the course code for the first one for those of you willing to and brave enough to play it:
A432 - 0000 - 01FE - 7FEA
"Kamek's Skewer Land". Word of warning: There are a LOT of Skewers. So much so to the point where the entire level is based around this one obstacle, with a few other things in your way as well.
