Space adventure Click the green flag to begin. Avoid the asteroids and aliens by using the up and down arrow keys to move your spaceship out of the way. Each asteroid you avoid gives you 1 point. Each alien you avoid gives you 5 points (aliens travel faster). Watch out: the more things you avoid, the faster they go! There are four parts to the "Space adventure" activity: Part 1: Asteroid belt Part 2: Speeding up Part 3: Keeping score Part 4: Add an alien (that's this part)
