I have played a couple of games. Need improvements but could be fun with some tweaks. AI make too much faults, the speed is too high. But animations are smooth and ok, the feeling when you hit the ball is nice. Slice, lob, passing shot, volley, aces, everything is possible.
Sound needs some work, and the high level (professional) is too easy.
Surprisingly, I'm quite enjoying the game. The players move smoothly, serving is straightforward (unlike TWT), and the game just feels good to play. The commentating is annoying, but that's not surprising. The player faces look weird, at least the ones I've seen, and are expressionless. Off-court, the graphics are pretty basic, but that could change in the final release.
