I really enjoy learning about pool, planning shots, learning about angles & caroming the ball. At some points I'd like to increase my skill by turning off the vectors, but you can't.
As a beginner, it would be very helpful to understand the rules they use. Every time I have played IRL, house rules have been slightly different. I've played this game hundreds of times and I still don't know the difference between US and UK pool, and I had to google 9 ball to figure it out.
Speaking of 9 ball, since you have to sink the balls in order, why is the numbering option normally turned off? Are we supposed to guess by color? Yeeps!
Lastly, I wish the self practice option let me play however I like, shooting balls in the order I prefer so I can practice whatever shot I want. Better yet, an option where I can set up balls as I like to work on issues or practice trick shots. And along the same lines, a Reset button, so I could try the same shot over to see what works better.
