Get ready to think in this binary number game! You start by landing on earth and coming out of your spaceship. To move your character, use the left and right arrow keys. When you come to a level number in the ground, push Z to play it. This will open up the level. A set of bars, representing binary numbers, will be on the screen. You have to click on them to change how they and the bars around them are filled. You have to keep trying to find different combinations until you find one that unlocks the next level and lets you keep playing!
