Fun mix of pool and golf. I appreciated you including a way to check out other levels if I got stuck in one, and there is a good number of courses. The physics of the balls were fun, especially with a really strong shot that made them bounce around wildly. I also like the addition of the shadows to give a sense of depth to the visuals.
One issue I kept running into is if the ball was near the edge of the screen and I tried to drag the cursor off screen, there wasn't a way to launch the ball once the cursor was offscreen. This made it hard to perform stronger shots at the angles I wanted. Here's an example of what I'm talking about.
If the cursor is offscreen, I can't hit the ball at this angle, so I had to move the cursor back on screen and settle for a weaker shot than I wanted.
Overall, nice job!
