The Lost Level Exit
With the Wii U offline for the past month or so due to a move, my Mario making has been getting a little rusty. But playing some old Mario games in the meantime, I was struck by inspiration. This one homages/shamelessly swipes the gimmick from one of the later Lost Levels stages. I suspect my tolerances may have been thrown off by playing a lot of Expert Mode in Mario Maker, but going back to Lost Levels, they don't seem nearly as unfairly difficult as I remember.
But anyway, now that I'm back online, I'm pretty delighted to see everyone has made a lot of stages--I'm looking forward to playing through the backlog!
