As a fellow cat-herding game maker, I absolutely had to play this, and I'm super glad that I did.
The game's super charming and looks+sounds amazing, even if I never really got the hang of the mechanics. I had a lot of trouble trying to figure out where I was trying to get the cats towards, and I think I expected the water to be shot from me in the direction I was looking, instead of appearing where I clicked?
I noticed some UI jank as well, with some textboxes and things appearing only half on-screen on my MBP 15", whether or not I was full-screened.
The funny thing is though, I didn't find myself minding any of that: I just really enjoyed riding around seeing what the cats were doing, accomplishing not much of anything. An excellent experience.
