Trekboer

You find yourself in command of the starship Trekboer as your adventure
begins. A deadly virus has struck earth and threatens the future of humankind.
In this mission you use the starship Trekboer to search the galaxy far and
wide for a cure before it is too late. Returning to Earth empty handed is not
an option.

Trekboer is a graphical interactive fiction game that uses standard single-
letter directions, N, S, E, W, for movement. You can also SAVE your current
location on cassette for restarting later. The command parser is a standard
verb-noun type. During your adventure you will encounter planets to explore,
teleporters, and warp jumps.
