The music is an instant 5/5, just too good!
My main thing is the difficulty curve at the start feels really steep. I spend like 40 shots on the first three jumps, with the last one feeling quite pixel perfect. Some subtle directional hints would also go a long way, got myself out of the course quite quickly by accident. It does not need to be hand-holdy, just enough so it feels like learning rather than trial and error. And yeah checkpoints please!!
But I'm a sucker for golf games so had fun regardless! Great job!
