Cute game. Makes good use out of the limited art style. The music fits well for a relaxing puzzle game. I didn't realize that there was a limit to swapping the lamp until I already ran out. In hindsight, that explains what that was gimmick in the first place. I caught on eventually when I saw the 0 and realized that was the number of clicks I got. lol Not that it mattered in the end because I still had enough cats to beat the level.
I also stumbled upon the little Easter Egg in the title screen by accident. Cute.
