Really nice visuals and audio. How did you get the chromatic aberration to work? It doesn't look like it's just part of the sprite, but it looks great! I like how the paddles move. Its a pretty small thing but it adds a lot.
The chromatic aberration is actually a shader (since Godot doesn't provide chromatic aberration out of the box) that's on a panel on top of the entiere game. I also made it so that it also gets stronger the farther you are from the center. So it looks a bit more dynamic.
