"With an average walkthrough time of 15 minutes, "Thing-in-Itself" is not a game in a traditional sense – it doesn't have win or lose conditions and doesn't present challenge to the player."
I know what motivates adding that to the game description.
However, let's be frank: a challenge, and chances of winning and losing, are always there.
It's just that the player himself has, in an introverted fashion, to define/become aware of them on his own.
