The art in this game looks really nice! You probably already know this but the ball going off screen is a bit annoying, so I feel like it'd be good to let you click and drag anywhere on the screen to launch the ball, not just directly on it. Also, it might be a good idea to make it so that if the ball is rolling extremely slowly, just go ahead and have it stop. I had a few moments where I was waiting for it to finally stop rolling and just wanted to hit it again. The way the ball moves and the particle effects on it make it very satisfying to hit. This is a really great start, and I'd love to see it expanded into something bigger!
