The graphics and sound were the highlight
Not much quality was put into the actual plot or animation, unfortunately. The only plot consisted of a couple of lines that sounded like generic anime tragic character lines, and the movement was painfully slow. You'll probably get a high score from others because they were impressed by the graphics and sound. It's easy to see that you put most of your work and effort into those two aspects, but those aren't the only aspects of a good flash work.
