This is such a charming little game! Definitely brightened my day.
There is certainly spinning involved! The combo feature is a nice touch although it's sort of out of the player's control as the spawns are random. Sometimes you just have to wait almost a full rotation and the timer runs out. That being said, it would be great to include some kind of indication for the combo timer and perhaps a button to speed up your spin. That way you can encourage players to spin faster to keep their combo, at the risk of missing due to the faster spin,
The visuals are delicious! Very cute and clean. The water provides a lovely background that isn't too distracting. There was a minor visual bug with the highscore overlapping with the [Spacebar to play] text when it first loaded, but that fixed itself after the first run.
It didn't really feel like there was a sense of seriousness anywhere, but I don't care, I had a great time. Great work!
