Reusage of fireworks
They were all the same firework, with dif colours or paired up. You need to create AS controlled explosions maybe. Or do a better job of drawing them. Also, this needs variety - dont reuse the same movieclip over and over - make a dif explosion for each one.
Also, u should make it so u click and the firework goes to that point - all this stuff isn't that hard to man.
good try though, u need to practise AS.
