use arrow keys (left arrow key, right arrow key) for player 1 use A and D keys for player 2.
this is my first project made alone with other projects coming up (now i know why it takes forever to make complocated projects). ver.1 pongs now work for hitting ball and for keeping score too! ver.1.1 fixed glitch with top paddle, also nerfed point in direction! ver. 2.0 Thanks to @squidbbibi for the revamp :) (you're welcome)
