It's very confusing that y'all are calling this a "game". There's nothing to play, it's just a simulation to watch.
See "walking simulators":

Plenty argue that these aren't games either (usual complaints involve lack of problem(s) to resolve, and no win-lose dynamic); but, then, what are these? The closest category I can think of would be "computer-animated film", but... these are interactive, and you can navigate and look in any direction you want, which yields a very different experience than watching a film like "Toy Story".
Minor spoiler: there's another tiny game hidden at the end of the third level.
