Fun little game! Here's my opinions:

- The high score disappears immediately so I can't read it if I'm too slow. It'd be nice to have a play again button so I can choose when to restart.

- The lerping feels a bit slow for a game that needs tight control. Maybe you're going for that, but if I'm moving my mouse fast, the ball lags behind.

I've tested it for some tries (my best score was 11,900). As a gameplay I find it quite easy to undestand and the increment of the speed between each star caught was fair to me.  Overall I find a pretty solid game with no intrusive music to be concentrate on the game, and also sound effects are simple but effective to this game.  Besides, I felt the black background was a good choice to be focused on the game, not being very intrusive with the game experience, either.

As a minor suggestion (to add a suggestion), perhaps you could add the Best Score on the game screen instead of being "hidden"  in the 3 lines option, and that it updates when the player while playing surpasses the High Score. As I said before this is a minor suggestion and very subjective. Some people may like, and others may loss the concentration during the gameplay.

In any case, the most important thing is that I really had a fun time with your game and it's pretty solid. Congrats!😊
