You are on the moon. You need to return to Earth.
Moonquake was prolific adventure writer's Laurence Creighton's first attempt at writing an adventure game according to his letter to Adventure Probe volume 8 issue 6. It was never released although he did produce a revised version in response to the playtest reports he received after submitting it for publication.
There are at least two distinct versions of this game - one dated "May 1989" and the other dated "September 1989".
