Quite a fun concept! I can see it becoming something like a roguelike golf if you could somehow create procedural generated courses. That would be super cool. Good work on the color palette. I think some sort of effect when swinging and a juicier sound effect would add to the experience. I played to the end and thought the courses didn't get too much harder. Maybe making some courses more difficult. Also, maybe adding a stroke limit will add some suspense and tension. Fun game, great job!
