In the 80s there was the boom of the so-called "gamebooks", interactive books usually of the fantasy genre, in which the reader was called to make choices and solve puzzles to reach the last page.
PROTEUS, a magazine released in the UK from 1984 to 1988, published a whole interactive adventure to play in each issue: they were naive dungeon explorations, treasure searches full of sense of bizarre, weird riddles and absurd monsters.
PROTEUS's adventures weren't masterpieces, but they were fun and damn difficult: there were often dozens of objects to necessarily find to complete the quest and defeat the final monster, and most of the time the decisive one was missing; furthermore, it was essential to draw maps ogf the dungeons in order not to get lost in the paragraphs, but these maps often... did not add up.
In short: a lot of fun for us kids of the analog era!
This is the soundtrack of the omonymous adventure published in “PROTEUS” Magazine (U.K.) in year 1987.
