Decent, not great, but decent
I don't really feel that pool should be speedy, but it's an ok concept for a game. I like the 3D aspect to it, definitely gives the game a great feel. A couple things I would recommend to do differently;
1. Allow for use of the keyboard to aim and shoot, perhaps using the arrow keys and space bar?
2. Provide for a couple of different modes, like a skill shot mode or untimed practice mode, or perhaps a tutorial to give players a feel for the game before actually getting into it.
3. While I realize that flash is very limited in it's ability to hold true 3D graphics, perhaps you could put a highlight on one corner of the ball (yes, I realize that round objects don't have corners, you get my point anyways). It'll look better without requiring more space, as reflection from a light source won't change when the ball rolls anyway.
All in all, I can tell that you have a lot of talent with flash, and I look forward to what else you put out. This just really didn't wow me overly much.
