Way too long and not enough variation
First of all, let me say that each one of you is good at animating sprites, and you have done an excellent job on each individual piece.
Having said that, I only enjoyed this cartoon for a little while. After several minutes, I began to wish that it was over already. Too many pieces were accepted into this collab. It should have been edited intelligently and made much shorter to keep viewer attention, because I was drifting off near the end there.
Most of the pieces were pretty much the same: Character beats up a defenseless and inanimate (yet annoyingly invincible) sand bag.
After I got bored watching the same thing happen over and over, only twice was my attention peaked...
Once near the end when the sand bag started fighting back, and when Wario FINALLY killed the little bugger.
I'd also like to bring attention to how the music did not fit the toon very well. There seemed to be two very long tracks that played over the entire thing. Individual music would have been better, as there were periods when there was a conspicuous absence of music, and at other times the music ran over already existing music (e.g. the tetris bit).
I applaud each individual artist's effort, but the way this collaboration was put together made it a little disappointing.
