Not really a 'game', but rather a (charming) web-interpretation of a technique called Oulipo, written by one of the founders of that technique.
It's CYOA-esque, but at each branch you're given some choices; to continue the story, change it, or end it.
It was interesting for the 5 or so minutes it takes to go through it, and I smiled as I did.
Leaving unrated since I enjoyed the experience, and learning about Oulipo, but I don't view it as a game to be rated.
