Wow! Lots of great stuff in this thread! I look forward to playing more of it. I haven't really posted much around here yet but I'm always looking forward to great Mario Maker levels ever since the game has come out!
Please try my levels too! I feel that these levels could be in a Mario game in that each stage relies on a central mechanic that ramps up in difficulty as the level goes on. It is not unfair nor is it filled to the brim with enemies. They can be challenging though! Good luck!
