Skyranch by Jack Driscoll

Note: This is my first attempt at a text game with my first attempt at my own text game engine.
I realize that it lacks a lot of features that other systems such as TADS and inform have.

The games excepts modest sentences like "give the first key to the guard" and "get the box from inside the desk and go west"

I guess I haven't been very great with planning of the game, but I tried only to see if I could complete one.
