I'm a real life pool player of 35+ years standing. Second, if this is a beta version, you have a LOT of work yet to be done. The "pvp" feature is silly. One shot each at a time? That destroys the momentum if the game. Now, the REAL beef. I use English a lot, and I understand it very well. Your English system is badly in need of an overhaul--the physics just don't work. Yes, I'm using a cueball capable of spin. It doesn't do what it's supposed to do. 2 stars for effort alone. Uninstalled.
