This is accurate gameplay from the Hitchhiker’s Guide to the Galaxy text adventure that INFOCOM made with the help of Douglas Adams in 1984.
I thought people would find it interesting to see the way a game would creatively do a demo in print in the 1980s since doing it other ways was either too expensive or not very useful from a marketing perspective.

It was very challenging. I never got all the way through it. Amazingly, it only covers a small portion of the first book despite taking hours and hours to play.
Actually, it was to turn on the light.
I knew a co-worker who was really into a lot of early and more modern text adventure games. He said the babelfish puzzle was one of the hardest puzzles put in any text adventure game, past or present.
