Make sure NmLk (Num lock) is on! (If you're using a keyboard). Player 1 uses W, A, S, D to move. N shoots weapon 1, and M shoots weapon 2. Player 2 uses Up, Left, Down, Right to move. 8 shoots weapon 1, and 9 shoots weapon 2. The smaller the square on your fighter gets, the less health you have. Don't run out of lives, or the other player will win. Reccomended using 2 keyboards to play.
