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.
Honestly, if you like text adventures, despite the difficulty, it's one of the most entertaining ever. Douglas Adams himself wrote most of the text, so even if you don't get very far, it's all funny.
I haven't read the novel, but I have played the game. When I played it, it was new, and it was really slow to load levels, which made it kind of a pain to play, but I did restore a good 3/4 of the ship robot thingy's face.
