Actually my bad I think the lag was meant to happen, right when I tap start, and then there is gap in time from when I tap and the ball move, it is just few milisec. I think you added it on intention to make the game harder
I really like the game because it's unique. I participated in the testing when the game was under development and I liked it very much since then. Great work!
Its a good game, I find that its a little hard to control the ball as it feels "unresponsive" when I tap and moves to fast when I hold. Other then that its a nice game.
