Very cool as a fellow golf enjoyer, but I may have hit upon a bug or two getting this score. There was a number of holes that I sort of just launched the ball through the wall off-screen and it seemed to give me an instant hole-in-one.
After reading the other comments I will mention that I do use firefox, which could be the culprit.
The visuals are great, I do like checkerboard grounds and autumn vibes so that gets a plus from me. The music is also solid and well paced for the gameplay. I do enjoy the simplicity of timing your angle and power, kind of like using a 3D golf game's systems in a 2D one. Fun overall!
