There is no new update since September and the game needs some physics tweaking . Noticed that occasionally players score a point while they shouldn't and that usually happens when the ball is trapped on the net and sliding down (I have a recording for with that happening if interested).

Compared to the original Hi-Res PC game (Blobby Volley) its missing animation, sound and graphic details (shadows, background etc).

The game is still fun to play but not much of a technical achievement than just an adaptation of a mini-game.
I still find it challenging in 2-player mode and I hope the development is not abandoned so that the scoring and physics glitches are ironed out. 
Would be nice to see some improvements on this game in the future.
