I know you said the beginning was stupid, yet that is not a reason to improve it? And why did you use pixel graphics? Terrible effect. The music was a bad choice as well; rock music tends to sound awful in Flash films. However, I gave you some credit (in violence) for the effective fight scene, which did save this film from being total bollocks.
For next time: expand on the storyline and draw your characters (if this is difficult then try getting a picture to trace around in Flash) and perhaps some scenery? (A black background is just lazy).
