I'm used to shooters but, for some reason couldn't get the hang of this. Tried all different types of techniques also tried to lower the mouse sensitivity since I thought it was too touchy but, to no avail this game just seems too hard for me. Not sure if others are having a hard time or not it seems even when I make "contact" with the ball it doesn't do anything!
Sorry the game is giving you some trouble. I recommend trying to keep your aim just ahead of the ball. Waiting for the ball to come to the cross hair is an okay strategy, but only works when you don't lose sight of the ball. Also remember that the orange shot has a very limited range. You can also play in the practice mode and lower the game speed to get a better feel for aiming.
In general, if you can play games like Quake or Counter-Strike, adjusting to VolleyShot shouldn't be too difficult, even if you're using a controller. Thanks for playing, and keep practicing!
