Cool game, I liked the idea of it. It felt intense and I felt the pressure on almost every level. I was able to finish it and wanted more, which is never a bad thing for a game jam game!
If you wanted to improve, I suggest making the ball bounce off of the walls instead of the game just ending, this would help make it feel more like golf and help make it feel more unique then other auto-runners. If you end up doing that, I suggest adding a timer and a 3-star rating system based off of the time. Other then that, I suggest making the music not restart every time, leave it as a continuous loop.
