This game recreates the Monty Python cheeshop sketch, which required asking about large numbers of cheeses.
The game is much more successful than most adaptations, as there is a natural puzzle structure here (figuring out what to sell).
I was put off by a moment of strong profanity which, however, is in the original sketch.
As other reviewers said, it's necessary to type quite fast. However, shortcuts are allowed (I.e. Typing part of a name).
