The sample games on the CD include examples of an opening game screen and a high-scores table. Use those examples to create a mock-up of your game's opening screen, high-score table, and the screen for the first level of your game.

Thus, your game should begin with the opening screen. There should be a "start" button of some kind, which loads frame 2 (the first level of the game). If your game has multiple levels, then trigger events should load the next level. When the game ends (in defeat or vidtory), the player should see the high-scores table, and have the chance to play over again.
