Hehe, this came as a surprise. Let me start by saying that I enjoyed watching this, and I found it very entertaining. Now to some feedback on the run itself:
Generally, this run was of high quality. Knowing the game well, I couldn't spot any major mistakes that cost you time. On the other hand, it was hard keeping track of everything that went on, with 4 players running around. :P Not to mention how impressed I am that you actually managed to produce a 4 player TAS. I am very, very impressed by that.
You also managed to create art without wasting time, such as jumping in different patterns before and after a boss. That looked nice.
There were some small mistakes I could spot, such as walking instead of jumping down edges, and not using the "jump through roof" trick I use I my run. All in all, the lack of these small details cost about 2-3 seconds at most, I think.
Another small complaint is the obvious lag. I am fully aware that you tried to minimize it, but even so, this 4 player run suffers from immense lag... It makes the run a little too slow.
Do I think that this should be published? Yes, it being an impressive, entertaining and well done movie. However, I don't think that this should obsolete
My run, because my run is 6172 frames (102.87 seconds) faster. I think that this should be published alongside the 1-player run.
EDIT: Oh, and I voted Yes, of course. :)
