Very polished pong, awesome!
Having all these settings in the menu is really cool (especially remapping controls)!
The game is pong, but somewhat juicier and very smooth, great!
I think either making the camera static, or zooming out the camera enough so the camera always renders the entire board would make the game even more playable.
The powerups are cool. Having them there in the first place really spices up the classic gameplay and makes aiming that much more important. I would have loved to see more, and more game-changing power-ups as well.
(Note: I’m not actually very good at pong~ :)
