Post a code for a level and I'll stream a playthrough of it in about an hour. One code per GAFfer. It can be for your stage or someone else's stage of your choice. Just quote this post with the code so that I can easily see it. First come, first served. I'll stream until about 6PM Eastern.
In the meantime, you could also give my first stage a try:

I wanted something in the SMB1 style that felt very un-SMB1, so this is a "vertical" air ship stage, to the extent that the game can let you disguise sub-areas as multiple segments, anyway. There are 5 distinct areas: ground, sky, outside the ship, inside the ship, and the captain's deck. It's probably too difficult for the average player, but I tried to at least keep the difficulty to precision platforming and not bullshit trolls. You can either see or react to pretty much everything that's coming.
