This is quite ambitious, not just for somebody who is fairly new to the forums, but for anybody. So far it is very good, I'm looking forward to the finished game. At first I couldn't work out the controls, but I worked them out eventually.
What I will suggest is to change the style of the left/right turning of the cue to abruptly. I made a
compass, you could use elements of it to get the angle of the balls.
