This is quite a bit more interesting than the pseudo 2-player run. A few things struck me as being possible sub-optimal, but many of them could easily be because I don't know the game well enough. The abuse of balloons was great, especially when you skipped the fans, but I wonder if you could have avoided the delay it took to kill both players. I also wonder if you could have had the slower player die in preference to holding up the faster one, especially in the first two casino sections. Finally, it bugged me that you picked up unnecessary boxes, especially right before going on to a new section. It's not a run-killer, but it is unnecessary and seemingly inefficient. Other than that and some suspicious letters showing up in the cutscenes, it was a pleasure to watch. The boss fights were things of beauty, the creative self-sacrifice was unexpected, the vertical area at the end of zone F was tight and the bonus stages were always interesting.
