For left Player (player 1) use W and S (W makes go up and S makes it go down), for right player (player 2) use Up Arrow and Down Arrow ( Up Arrow makes it go up and Down Arrow makes it go down) - Enjoy. Also if you are feeling o.g i think you will like this spin-off of a game that was released in 1972.
Credits to me (Suyash) For making the game.
