I'm not really sure how to rate this since I'm not sure if it isn't even a game and I don't mean that as an insult. Watching a train moving slowly in what appears to be procedurally generated world can be very stimulating, but since there's seemingly no interaction, I'm not sure on how to grade it, so I'll refrain from doing so. It is a nice experiment and definitely very unique take on a limitation and I had fun sitting alone with my thoughts watching that train go.
