Very cute! I loved the comic art and the music was sooo chill! But, somehow, two games in a row, I got the ball stuck up at the top... so the dog and I just sat staring at each other while the ball rolled back and forth between us xD there should maybe be a slight amount of gravity on the ball or a "bounce" mechanism off the top and bottom walls (sorry for the clumsy language - I'm really new at coding and haven't made a pong game before lol so I don't know what would need to be tweaked exactly).
All in all, I really enjoyed playing!
