Lunar Lander is a text-based computer game. The goal is to land a ferry on the moon. The height, the speed and the available fuel for braking will be displayed in sequence. Afterwards you have 3 seconds time to enter the fuel used for braking. The new height, the new speed and the remaining fuel will be calculated. Thereby a braking period of 10 seconds is assumed. The cycle is repeated until the ferry landed. A landing at a speed less than 3 m/s is considered as success, about as crash.
Lunar Lander was written by Jim Storer 1969th. The version presented here is inspired by the pocket calculator versions popular in the 1970th.
