Cool idea to make a pong game with the theme. Gameplay is obviously fun, since it's pong. Powerups were cool too. I also really respect that you made both a 2 player and vs AI mode.
There was however an exploit that is kinda overpowerd. Basically since the value of the dice increases per hit, most times you score, you gain 6 points. Once you got a 13 point advantage, it's impossible to lose. If you let every dice into your goal without hitting the dice back, the opponent can't make more than 12 points and the game will end with you as the winner.
Overall though, nice game!
