Good attempt especially considering that it was created on weekend only. Could be a bit more chaotic. Maybe a bit more effects or background music. Maybe some 'wow effect' is missing here.
But still it's a fresh look on Pong. At least I haven't seen it before.
p.s. as an idea, I first thought that the ball will destroy black cell if touched, so a player must protect blacks while destroying blues. It might make the game too hard though, but who knows.
