It took thousands of attempts!
This could be the toughest Mario Maker level around!
It was made by a user called Pangeapanga and it even took him a whole six hours to complete.
The rules of the game say that the creator must complete their own level before putting it up online.
Once the level was uploaded it took an amazing 11,000 tries before anyone could finish it!
We’d definitely like to see Sean try it out over on his YouTube Channel!
