I really nice game! The graphics and sound were amazing and it was really original and fun! It was a bit too frustrating to me though. I ran into some bugs where the ball wouldn't aim towards my cursor, making me take up to 10 or so extra shots trying to correct it. The ball going airborne was a bit annoying too, as it meant I had to take several tiny shots if I wanted to make it under a windmill or through a tunnel. The levels were beautifully crafted, and overall, it was a really good experience, great job!
If you have time, maybe consider checking out my game too.
