Graphics are nice and clean. No sound, unfortunately, I would've really liked some nice beeps and boops for when stuff happens. Gameplay is okay but the paddles are way too slow, and if the ball moves too close to straight up or down, it becomes near-impossible to properly track it. Limiting the ball's possible angles to about 60 or so degrees as the steepest angle in any direction would probably mostly solve the latter issue, and the former issue is solved by, well, making the paddles faster, or maybe making the player's paddle mouse-controlled to allow for more precision while also allowing for fast speed, and then adjusting the enemy paddle accordingly.
Fixing those issues would make the main twist of the game a ton more fun for the record, and speaking of which, the main twist of the game is actually a nice touch. :)
All in all, a fairly decent attempt at demaking Pong out of all things, a game which by all accounts is not one that is easily de-made.
