Maru must choose between boxes!
On the surface, this appears to be yet another cute-cat video superimposed upon a gaming metaphor. However, when we dig a little deeper, we see that this brilliant and incisive piece lampoons the choices we must make at every stage in life, about every aspect: Do you choose the plain-looking but comfortable box or the pretty but impractical box? Ultimately, we must choose a box, and by deliberately not choosing a box, we are still living a life defined by boxes.
Or it might just be about a cute cat choosing between boxes.
