I personally enjoy this idea a lot.

Yet technically from the standpoint of a gamer to have fun I am missing a clear win and fail state. When do I know that I have won the game? When do I know that I did fail it? If there is an aim there should be some kind of "you won the game" possibility, since this game seems not to be a linear one, choice might have not much impact if the game doesn't give positive or negative feedback.
