This was a really interesting concept, and I loved how you twisted pong to fit the theme! The graphics are simple but really stylish, and the ball multiplying was a fun surprise when I discovered it. The gameplay is really simple but that's what I find fun about it. The pixelation effects were super good as well.
I did find one small bug though, where if I tilted and held a paddle and multiple balls that are aligned with each other (so that they hit the paddle at the same time), some balls would end up on the other side and start multiplying by a ton.
All in all this is a great take on the theme, good job!
