At first I thought "huh, is this just another Pong incremental?" but I saw the other comments and figured there was more to it than that. I'm glad I stuck around, what you have here is pretty brilliant and I'm glad you didn't spoil it in the screenshots :)
The overall concept has the most potential I've seen so far, though that's partially due to the short nature of the game leaving you wondering what else you can do with the game. Regardless of what it could be, what you have here is incredibly tight design where the mechanics work well with each other. It would be difficult to keep piling more and more on but I think it could be done with some clever thinking which you're capable of.
Even without the meta stuff, the core game mechanics are already well done. Having the left paddle incremental gains was the first nice moment, but then the right paddle splitting balls was an even better highlight and kept me wanting more. Excellent entry and a good representation for the future potential of the genre.
