So little happens
This was rather unertaining to watch, because really nothing happened in this. It was just Sonic and Knuckles touching each other in odd places to form a fight of some kind. Wow, I just realized how dirty that sounds. While the coloring is not the worst, you should have some stuff going on. I guess it was supposed to be a non-sequitor anti-climax thing, but it just didn't work for me. I know realize the humor of your name having "chili" in it because it's Sonic's favorite food.
It kind of reminds me of how I just went to Sonic for dinner tonight. But I digress, this should at least have some better sound, although the song wasn't too bad. The one thing that was a bit interesting was how it led up to itself. It is just that a lot of flashes submitted are so unique and anti-action isn't what we want here. An actual fight would be more enjoyable.
