I played this game on my iPhone, and it runs well, no lagging or issues. I like the glow effect when the ball hits the other balls, it’s a nice touch. Some more sound effects, music, and bounciness (when the ball hits anything) could help make the game feel more alive. Maybe it could be worth changing the gravity settings a bit as well? I feel like I’m playing golf on the moon :D
The foundation is good, and with a little bit more juice, the game can become extra fun. Good job on the game
