This is a 2 player tank battle game I have been making in my free time. Player 1: up and down arrows to move, side arrows to turn, and m to shoot. Player 2: w and s to move, a and d to turn, and q to shoot. I recently figured out the bounce physics, so the bullets bounce realistically! It was a little hard, but it is actually pretty simple. By the way you can't turn into a wall.
