Try to avoid the asteroids or tap right, left or above
your lander to fire at them.
Tilt the iPhone or iPod touch in order to control thrust.
You have to land on the base with all 3 lights (position above base, fall velocity and angle) in green condition.
Gravity increases as you get nearer to the planet, so don't get the wrong impression when you fall relatively slow in the beginning !
The radar on the left shows the actual distance to the
surface of the planet.
Status bars on the right : remaining fuel ('F') and fire energy ('E').
Your start-level can be selected in the intro-screen ;
the number of asteroids and size of the base change in the higher levels.
