The Engine

The background needs to be a transparent color.
Give me an example of the sprites you are talking about though. I could program it in where you can set the background color the be drawn as transparent.

The Intro animation is strange to work with. I haven't tested it for glitches, but, you should still be able to see the animation play through if you set the first frame to have:

Code:

function EnterFrame(){
    gotoFrame(char.frameNum+1);
}
setEnterFrame(EnterFrame);

And the last frame to have:

Code:

function EnterFrame(){
}
setEnterFrame(EnterFrame);
gotoFrame(char.frameNum+1);

This makes the animation will stop playing on the last frame and stay there until the countdown is completed.
If you want to make it repeat something change it to just:

Code:

gotoFrame();

And type in the frame number you want it to repeat to.
