Scenes from a handful of ordinary lives alternate with chapters of a child's colorful science-fantasy. Sweet and sad, and complex enough that you may need to go through it twice in order to fully understand how all the fragments fit together.

Very story-driven, with menu-based conversations and virtually no puzzle content. It isn't terribly interactive - indeed, you're practically driven through it on tracks, and any actions that you don't take tend to be rendered unnecessary. But the story is intriguing enough, and well-written enough, and moving enough, that this seems a small quibble. This is probably the most successful example of interactivity at the service of fiction, rather than vice versa.
