Thanks for the review! I am glad you enjoyed playing the game :)
And yes, I can 100% agree that the values for the movement speed of certain objects like the ball, paddles and projectiles still need some fine-tuning before I can create an enjoyable gameplay experience that is neither too challenging nor too easy. (But maybe I should think about adding a win condition first. Otherwise, game journalists will start calling it "The Dark Souls of Pong" because they can't complete it :P) At its current state, this game is a little rough around the edges (to say the least) but it is probably going to become one of those projects I will return to every now and then to make some improvements whenever I have the extra time.
