The cats slide around not on the 64x64 grid, which makes them look smooth but breaks the rules :) As noted, there's not much of a sense of agency here; I don't feel like I have much control over the cats (arguably, because they're cats), but that does mean that the game feels like making a succession of random moves until you win by accident, rather than by superior play. I can't see how anyone could become an expert at this game rather than merely winning by luck...
