I'm just starting out with Flash and am creating a few little things. So far I've been building them on the main stage/Scene 1.

Now that they are getting a bit more complex I see this isn't the best way to organise things.

What is the best practice? Should I be doing each part of the game or project in a separate movie clips?

Then bring them onto the stage or activate them through action script?

The walk-through for my project is like this:
start screen: choose a game
game screen: complete game, move onto next game screen
and so on.

Would each game be a movie clip or how should it be organised?

You can see I'm already having trouble with this approach here:

Are there any guides or tutorials on how to organise things? I'm following the Lynda.com videos on Flash at the moment but so far it hasn't come up.

Thanks!
