It was good for your experience man.
You have some enthusiasm for this simple as that sort of thing. I liked the idea, but the animation was just a bit... boring. I mean, it sure was simple. You can still be simple but complex at the same time by using only squares to create all sorts sf stuff. Use filters on your flash, use coding to make the bounce around *contct if you need help with any of this*, make them change colors.
Also, some of your colors were not very niuce to look at. Like green on yellow or blue on brown. I did enjoy the tweens though.
So anyway, I gave you a 5 for the obvious effort you put into this and an 8 for what I think you deserve at your level. I mean, you are after-all only 14. I was at the stage of drawing stick figures at 14... I sucked at animating. xD
Great job old bean! Keep up the hard work.
