That does not need to be the case (seeing that you probably meant this in jest, I still will take it on). Assuming the cat is already a higher dimensional being, which I feel is valid as it can move between them.

Imagine a Cube going through a 2D plane. You would see a cross section of the cube depending on the angle it goes through. The same would be the case for a hypercube in 4D and 3D (different effect as different cross section though).

So I would argue the comic is correct.

With heroic, GOG games work flawlessly, you can use both proton and wine with it. Also supports Epic Games and other games from launchers.

Native GOG launcher on Linux would be nice, too though
