For 1v1 use WS and up and down arrow. (Player 1 is on the left and Player 2 is on the right). For bot use your mouse for up and down and you are on the left. To reset click the green flag. If the ball gets stuck behind your paddle, just move your paddle. Also, the ball is supposed to be lighter and then darker.
THIS PROJECT WAS RESHARED AND THE ORIGINAL PROJECT WAS DELETED!!! @Zinnea for a bit of the code for the ball. @wabbit_III for some code for the bot in his remix. PLZ Heart and Star I worked for 5 hours on this. New update August 28th: Shows your username if you are logged in. New update October 14th: Major bug fixes.
