Another entry with a nice visual style and a good concept on the theme.
As mentioned by others, the controls aren't ideal. I think a way to remedy the issue with the controls is click and hold to start spinning, and release the mouse button to release/throw the ball. That way you can't accidentally click outside the game window, etc.
Would have loved to heard some audio in the game! Can imagine there being some cool sound effects as you throw the ball, it lands, the crowd cheering, etc.
Hopefully you can flesh it out a bit more, and I look forward to seeing it with some improvements! Great concept, though.
