Use A & D for the blue player's left and right controls. S launches your spear, and W & E angle the spear. You can't jump. This is intentional. Use Left & Right arrows for the red player's controls. Down arrow launches the spear, and N & M angle the spear.
I came up with all of this. I did all of the sprites on my own, and the concept was mine. Please let me know what you want me to add. Please Love and Favorite!!!
