Thank you very much for your feedback, but for now, this was just a little project, it was nothing big to expect, it was just about having an incredible hard version of pong, and if I have enough time, I will definetly change this, but I'm not so good at programming some custom AI, so, you probably can't expect this, but I'll do my best to fix it.
Said that I'm a very young student who just wants to make some cool games, more like an exercise for the future, and I appreciate your good ideas but for now, I can just tell you to try some of my other games, that are way more advanced.
I can only say "Thank you!".
And: The game is not fully "unbeatable", other people got it after about two or three hours of trying.
If you want to talk further, you can send me an e-mail: firstname.lastname@example.org
Or you join my discord, the main language is german, but you are welcome speaking english too!
I also made some android apps by now, check them out!
