I'm surprised
A lot of people have already pointed out that the animation is a straight trace from the actual game graphics. They're partially right, but these sprites are not actually hand traced but auto-traced using Adobe Illustrator.
You can discern this by looking at the jagged quality of the lines. Doing an auto-trace requires no effort at all, which would allow the author to rapidly slap this together in a matter of an hour or two.
Had you hand-traced the individual assets, I'd be more inclined to give you some recognition - considering that would imply that this was a practice run.
I surmise you spent a majority of your two months learning how to actually work in Flash.
I learned this lesson years ago: you don't submit quick, one-off school projects to Newgrounds. It'll get ya slapped upside the head by a nice sum of people.
