A) there is no backspin in this game to speak of, really... a couple of stabs at it, but nothing yet.
B) dying at the hole is subjective to your POV. Trust me, the machanics of the game know exactly where the ball is going to be before your club loses contact.. (why do you think the "heartbeat' starts in the CTTP competition upon striking the ball?)
C) the reason the ball can be aimed left and goes right is called the 'beast'.. look it up on the search feature over there --------> (it's not a bug, it's a feature!)
D) The game is in beta, and it's free, and no one forces you to play. If you think you would like to help out with constructive criticism, and valid product suggestions, I am quite sure that WGT would love to hear from you. There are a number of very valid discussions going on right now that will keep this game growing and 'rock'ing for years to come.
Hope that helps.
