Here's your official Iron Man thread!
It took me about 200 deaths before I managed to get from 1-1 to 4-4 in one go. After that it took me another 50 or so before I was able to do it again. The catch is, the second time I happened to be streaming live and caught it all on video!
Anyone else manage to put a wrap on this game yet? Leaderboards suggest the amount of people who have completed it is pretty low. I'm still working on some of the extra content, like the City of Gold, etc.
