Very bad
Also it is nowhere closely related to the Black Ops game which isn't very fun in my opinion but whatever. This piece kind of just sold itself short as not very creative and having very childlike humor as well. Farting may be funny to some but not all and this seemed to be an endless yet annoying loop that is poorly done on purpose as well.
The intro where the national anthem is farted was funny for a moment and then it just turns to something poorly drawn wearing a sombrero and going up and down in a simplistic manner with a farting bit coming up from time to time.
Some suggestions would be to spend more time and slow down, it is not really a race trying to rush and get it done. Take some time, spend more time animating each frame and you actually stand a better chance of getting a higher score.
Overall, not very well done and just an endless loop with some fart related humor added to the mix.
