    private function placeHomeTitel():void
    {
        homeTitel = new HomeTitel();

    }

    private function placeInstBtn():void
    {
        instBtn = new InstBtn();
        addChild(instBtn);
        instBtn.x = 275;
        instBtn.y = 225;
        instBtn.addEventListener(MouseEvent.CLICK, gotoInstructions);
    }

    private function gotoInstructions(event:MouseEvent)
    {

Answer 1

Seems like you never remove level1 from your menu. Even though you remove all children from Level 1, the movieclip will still exist and be on top of your menu.

I would recommend reading though this tutorial, as it will teach you some basic skills about structuring your code, and specific game development features (sound, preloading, saving things in cookies): http://gamedev.michaeljameswilliams.com/2008/09/17/avoider-game-tutorial-1/

Answer 2

I think you should rebuild/redesign the structure of your game.

Now, your code does few strange things:

• in your Main class: everytime you call function gotoLevel1 you create a new instance of Level1
• in your Level1 class in the function level1Opn you create another instance of 'Level1' and you add it inside Level1 - quite a mess.

This isn't just small code tweak - you should rebuild it quite significantly.
