it is getting better with each iteration sir...well done.
i agree with genkigenga that a level of added polish would be added sounds for accomplishing certain things like a hole using the jumps, hole in one.
GenkiGenga, to your question, he did have a mechanic like what you suggested in one of his earlier versions, but he changed it to this because it allows the player to change their mind about the shot, instead of being stuck with shooting, once you have set up the 'shot'.
i also agree that a numeral indicator for the angle would help with fine tuning shots as well. you could have the number inside your 'arc' graphic, to the right or front of the player.
this is really coming together nicely.
keep going sir.
