Review.
Pros:
It's pretty good for your first animation, the shooting effects, zooming, etc were great for it being your first flash submission to NewGrounds.
Cons/Recommendations:
It's very short, and misleads you into watching it over again expecting to have "Rule 2", but it's only a single loop. I recommend you add a replay button as the music also starting overlapping over it's self, and this could probably easily be avoided with a replay button.
It's not drawn very well. Lines are unfinished, some lines are bigger than others, etc. It looks bad and isn't done very well. I recommend you make the lines look a bit better. The gun is also really low quality, I recommend you redo it so that the quality isn't so low.
