I'm reminded of Lonely Company, another game in this jam. This feels really polished and would be great with a second player. I don't have one to play with at the moment, so I apologize I can't give more in-depth feedback. I'd prefer if the ball was bounced off either paddle but matching colors gave a multiplier for score. It would certainly increase the chaotic factor, and make singleplayer coordination much more manageable.
It's hard to comment much on a classic like Breakout because anything I could say about it has already been said. Good work.
