Astro barrier

When you get to the opening screen of your game press 1, 2, or 3 to skip to levels 10, 20, or 30. 
Secret basic levels can be played by waiting 30 seconds before the start of the game. When the screen is explaining information on the orange lever, shoot the blue ship that goes by. This will give you access to the secret levels. There are secret levels in the Astro Barrier mini game at Club Penguin. To get in to these expert levels play up levels 10 or 30. After level 30 and before level 10 you cannot access them. Before you start one of these levels just wait at the opening screen for 30 seconds. Keep an eye out for passing ships. When you see a blue ship come by, shoot it. You will now have access to the secret levels.
