Very nice! The VFX are great and match the graphics well. The classic mode works as you'd expect, but it would be nice to have a bot to play against as well. The defense mode is easy to understand, fun to play, and doesn't feel out of place in a Pong game. The music is a little quiet by default. I only encountered one bug, if you switch directions in one frame you don't lose speed. Overall, a very good game.
