Also noticed there is no ground after 9xxx meters :p
yep I got the problem, in unity i used Update constructor to do this job which created this problem. I think I have to replace using couroutines maybe. Thanks for finding the issue as I had the same issue when I was testing the game. Actually in that high speed the ball might cover long distances but the ground may not reach that extension. That is a result of the high speed of the ball. Otherwise it would be fine under normal cases. Thanks a lot for playing the game I have learnt something important. Thank you !! 😁
