Making a two-player game was a neat idea. I noticed that although the instructions say the first player to reach 10 points wins, the game didn't end until I reached 14 points. Also, it would be nice if the game didn't start immediately when the page loads, so that the player has time to read the instructions. But overall, this is fun.

The game being set to the right of the screen feels awkward, the pong ball moves too fast and it feels too difficult. The up and down arrows scroll the window which makes gameplay difficult.
