Challenging and fun
Firstly, let me say this, I was playing with a touchpad on a laptop making this about a hundred times harder, but not impossible.
The art was absolutely incredible (pastels?) and I loved the jazz type music you threw in there. It definitely calmed me down when I got those *ahem* few errors. :P The gameplay itself was clever, as well as the changing shape of the pathways made me understand that clever cat's movements (eg a swoop, a stalk, etc).
I am taking off a point because for some reason the pathways stopped appearing about halfway through the kitchen area. I'm sure it's fixable, but until then, this game isn't perfect.
