I am the master of the ball muhahahahah.
So the game has nice art, nice music (though short), and the leaderboard / onboarding is always nice to have.
I wasn't particularily a fan of the game because it featured a bit too much randomness for me (to invest in for better scores I mean). However, I really liked the chaotic experience when you reach a certain point and you have too many balls to manage 🤣
Other than that I think you could add some more dynamism by giving the balls some more weight and increasing the flipper strength to create a snappier experience.
