Cannot make bullet shoot right

Nomatter what I have tried for some reason the pullet refuses to shoot to the right or to the left. It is starting to get really annoying. All it keeps doing is shoot upwards and nothing more…

public GUITexture AtkText;

public Transform projectile;
public int speed = 20;
public bool cooldown = false;

	foreach (Touch touch in Input.touches)
	{
		if(AtkText.HitTest(touch.position) && touch.phase != TouchPhase.Ended && !cooldown)
		{
			Transform clone;
			var rot = projectile.rotation;
			projectile.rotation = rot * Quaternion.Euler(0, 0, 90);

			clone = (Transform)Instantiate(projectile, transform.position, projectile.rotation);
			cooldown = true;
			projectile.rigidbody2D.AddForce(projectile.transform.right * speed);
			clone.rigidbody2D.AddForce(clone.transform.right * speed);
		}
		else if(AtkText.HitTest(touch.position) && touch.phase == TouchPhase.Ended && cooldown)
		{
			cooldown = false;
		}
	}

if you are trying to make it shoot where you touch, why not find x and z coords of the touch point in world space, and instantiate the projectile, make it projectile.transform.lookAt(new Vector(x,0,y)) and add force to it in the forward direction.

OK apparently I was really stupid when it came to scripting this =.= but for future reference and for anyone else here is the fix:

			cooldown = true;
			if(facingRight)
			{
				Rigidbody2D bulletInstance = Instantiate(projectile, transform.position, Quaternion.Euler(new Vector3(0,0,0))) as Rigidbody2D;
				bulletInstance.velocity = new Vector2(speed, 0);
			}
			else
			{
				Rigidbody2D bulletInstance = Instantiate(projectile, transform.position, Quaternion.Euler(new Vector3(0,0,180f))) as Rigidbody2D;
				bulletInstance.velocity = new Vector2(-speed, 0);
			}
