Wander [incl. Castle] © 1974 Langston, Peter.
Tool for creating interactive fiction. It comes with one text adventure called Castle.
The player wanders around without much of a goal exploring locations such as a forest, orchard, missile silo and a castle. The player types text to go places and pick stuff up or otherwise interact with elements in the environment. There is no scoring.
It was continuously updated into the 1980s.
