Game Theory Question

I sorta just jumped into the main “frame” of the game, becasue this is my first go round at flash.

Eventually I vision this simple game to have 3 screens

> Play Mode
> Game OVer

Right now, I’ve got the play mode going, and have lots of dynamic move clips being added to the stage.

I was wondering the best “garbage cleanup” way to end the game when an action happens?

Woud initalizing a new clip be the best? Or do you usually just track everything on one frame with conditions?
