The game is very well designed, buuuuut……..
It is soooo hard! The first level is extremely easy and then I started level two and it is almost impossible! I suspect that the players aren’t even real. Most of them go to the location I am aiming for my serve before I even make it (which is not supposed to happen since I can’t see where they are aiming). They can even predict where my silther shot will end up which would technically be impossible for a real person. If you remove the AI opponents, I will change the rating to 5/5.
