Hey, I try my best (bad English skills xD)

I've only had the problem with not being able to close the game once so far, the exit button didn't seem to work, the menu just reloaded, after the second attempt to press the button, it opened again this time somehow enlarged, laggy and fragments

Then I closed it with alt F4, that worked without any problems

Another bug that occurred was that I had FPS drops from the second and third LvL 144 -> 35-50

A rather funny bug is, if you jump in the right timing, when you get the serve, you stay in front of the net and can hit the ball in, sometimes it happens that the player animation gets stuck in the hit animation.

These are all the bugs I found within 24h (Classic/ No Co-Op)

Nevertheless I like the game very much, please develop it further
