Tiny terminal based lunar lander game, ported from the 70s.
A spaceship simulation: your job is to land the Apollo lunar capsule on the moon. This is a port of the original lunar lander written in FOCAL. Original source code: http://www.vintage-basic.net/bcg/lunar.bas.
It is ported as close as possible to the original source, so don’t take this as idiomatic Rust code :-)
There’s also a Go version on bitbucket.
