Instructions on Game Play
The goal of
the game is to safely land the moon lander on one of the four surfaces.
If the lander makes contact with the ground, and has a low
velocity it will be safe, otherwise KABOOM!!!
Every few seconds a prompt will ask yor for control
instructions. It will ask you to set the main, right, and left
thrusters to either high, medium, low, or none. The rockets will
continue to fire at those settings until you are prompted again.
At each prompt, you can adjust the rockets accordingly.
"Main thruster" is a rocket motor under the ship that provides upward
thrust.
"Right thruster" is a rocket motor on the right side of the lander that
pushes it to the left.
"Left thruster" is a rocket motor on the left side of the lander that
pushes it to the right.
