Zodiac is a text adventure in whcih you have to explore the twelve houses of the Zodiac, along with a maze, as well as killing the Ice Giant and fire-eating dragon.

In addition, you have to pick up useful objects along the way, and use and then drop them as you make progress.

The usual NESW and up and down commands are available, but in addition, to make Zodiac an absorbing, but frustrating adventure, there are a number of key words that you must discover for yourself.

One of the most difficult is how to get past the bull in the House of Taurus - a problem which I wrestled with for a long time, along with a friend who has the same program.

We eventually solved that one, but so far we have not been able to overcome the obstacle of the Ice Giant.

It looks as if it will take many more hours of keyboard word before Zodiac is eventually solved, but if you cannot make progress, A&F will provide clues.
