To control Player 1 (the left lightning bolt), use the w and s keys. The w key will make the bolt go up and the s will make it go down. To control Player 2 (the right lightning bolt), use the up and down arrow keys. The up key, hence the name, will make the bolt go up while the down key, also hence the name, will make it go down.
Note: YOU NEED TWO PLAYERS TO PLAY THIS, THERE IS NO ROBOT PLAYING FOR YOU Note: You have a few seconds at the beginning to get ready. Note: The pink lines will end the game but you can still move the bolts. Idk if it's a glitch or something but plz don't mind it, thanks!
