This game is amazing. Nintendo never needs another 2d Mario game as far as I'm concerned. Anyway, I have 7 levels right now. I'll just post the code to the 6th level because no one has beaten it yet. I didn't know it would be so hard, but I bet vgchartz is up to the task. Hopefully, you can find the rest of my levels once you search for the 6th one...at least that's how it should work. I never really use Nintendo's online network. This game has given me a reason to play my Wii U again.
I'm going to go back to the beginning of this thread, and start playing through your levels. I prefer SMB3 levels, and levels that are mostly realistic Mario levels, but I'll play anything at least once.
P.S. All of my levels are SMB3 levels.
Edit: I just looked at the second post in the thread. Here are all my level codes.
