SMB Jetpack Lua ... thing
This is nuts.
Anyway, it demonstrates/abuses the low-gravity mode from my previous video.

How? Well, let's just say Mario can't jump any more! The A button turns on a "jetpack" like thing, that accelerates him upwards for a short time.
Then I took it a bit further and took out his ability to walk on his own; in short, Left and Right now (slowly) accelerate him in their respective directions, while holding down B boosts him at five times that pace (although it eats fuel).
One interesting aspect of nuking the game's normal movement is that you can move around when you aren't supposed to be able to (as this prevents button input while changing Mario's acceleration values directly).
And yes, I beat the first level during the demo.
