I've been playing Super Meat Boy for about 4 months now and got pretty good at it. I decided I wanted to do a proper Impossible Boy Iron Man speedrun just because. Here it is:http://www.youtube.com/watch?v=Xz0REuBK154
This one is a "pure" Iron man run: correct level order, no "Exit to map" trick and, for the most part, fast level strategies. I'm also proud to say I came up with all the patterns/routes myself (although I had to slow down in some places). Apart from a few glaring execution mistakes, I was pretty happy with the result. WR, maybe?
Hope you enjoy!
