Funny concept.
The art style is pretty cool too.
I like the fact that the points change over time even when the scene is static!
Did you used a point cloud shader, or something else?
I also feel that your game would be perfect to tryout clayxels.
In terms of gameplay, the only issue to me was that it is hard to see the ball hitting the paddle.
Maybe orbit the cam a little bit around the paddle and tilt the paddle a bit more?
Also, I don't know if it was intended, but you can double click everytime the ball hits the paddle to make double points :p
Overall Good Job!
P.S. This was my best score and took me ages to get it :(
