linesplits and how do u do them

i played the game for 2 years still i cant linesplit

so bascically u have to freeze movement like in agario
without the button

put yr mouse in the center of your cell until uve completely stopped and then u move it slightly toward the direction u want to linesplit

u can check that by pressing w and confirming the direction...oh and u can not 64 vertically but u can easily 128 line horizontally
