The design is super polished and the cats are adorable! The running sushi concept is also something that immediately gets your attention :) I probably wish that the gameplay was a bit less random as I got some orders in the beginning of the game that I couldn't afford, and it is hard sometimes to predict which cat is going to eat which food. Maybe it would be nice to have several levels where at first there is few cats and orders! I ended up serving random meals and my cats were always about 44% happy without changes.
All in all, a beautiful entry!
