mattin created a new video which shows ELFrun from starting it up on the iPhone to finishing a level (and most of a bonus level). It’s one of the easier levels at the beginning (level 5), so there are not many obstacles and the speed is still pretty low. I guess playing a higher level through a camera is pretty much impossible.
ELFrun is also currently featured on TouchArcade.com, hooray!

I was a bit scared how fast ELFrun was pirated, though.
