Thanks so much for your entry! Yess, I thought about adding an invisible wall, in fact, there's one but it seems like the collision doesn't really work, cause the ball just goes away. I though about reseting the ball x and y to initial position, but couldn't do that on Godot, I'm new with the engine, so there were some things that couldn't do. I guess in the future I'll learn how to do that, and hopefully, fix some of those aspects of the game. The idea of a pong game playing as a background for the menu is pretty cool! Thanks a lot!
