Lunar

_Lunar_ is the original Lunar Landing game. The player’s aim is to
successfully land a lander on the moon’s surface. The game plays in turns
which represent one second and is completely text based. In each turn the
player is asked to determine the rock fuel burn rate, which can be between 0
and 200. The velocity, height above surface and remaining fuel is reported
back to the player. The aim is to have a controlled landing and the player
must make sure his velocity was not too high when the surface approaches and
thus not run out of fuel prematurely. When the surface is reached the player
is shown his remaining fuel and landing speed. If the player runs out of fuel
the game continues with second to second updates, but no longer accepts input
from the player.
