The Spark is great in all the things that graphical artists value. It looks jaw-dropping. But it fails for me in the story-telling aspect of it. What is the story of The Spark? A character falls down a hole and finds there a clue. And because of how utterly bored he is, he decides to follow that clue until reaching a place where he finds grass. A thing that he was programmed to find. Yes, it is not as straight forward as him just walking there by himself and finding the grass. There are obstacles along the way, but non of them make any impact.
