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.
I spent days on it. I did finally get the Babel Fish. I think with help by talking about it with friends who had solved other parts of the puzzle... but it got even harder after that!

First you had to put together the improbability drive, then you jumped into different characters' bodies and had to survive in their bodies AND bring back the items you need to make it an infinite improbability drive and I didn't get past that, but apparently after that, you land on the planet Magrathea and you have to figure out how to get the door open and that's where the game ends.
