First player (on the left) uses the up and down arrow keys second player (on the right) uses the w and s keys if you are reading this the score is broken, I hope to fix it one day. (ello this is HeyitsFelix from two years in the future I just fixed the score and OH MY GEEZ it was so easy I should have fixed two years ago)
There are better pong games, do not play this one or you can.
