My bullet only fires in one direction.

I've seen people with similar issues but I haven't quite found a solution yet. my bullet fires fine but only to the right. It's a 2D metroid type and the bullet is supposed to shoot in the direction the character is facing (the bullet also has to flip because it has a fire tail that can't face backwards) here are my player, bullet, and bullet forward scripts.

Player code:

 using UnityEngine;
 using System.Collections;
 
 public class RobotController : MonoBehaviour 
 {
 
     // how fast the charecter can go at max speed
     public float maxSpeed = 10f;
     bool facingRight = true; 
     
     bool grounded = false;
     public Transform groundCheck;
     float groundRadious = 0.2f;
     public LayerMask whatIsGround;
     public float jumpForce = 700f;
 
     // Update is called once per frame
     void FixedUpdate () 
     {
         grounded = Physics2D.OverlapCircle(groundCheck.position, groundRadious, whatIsGround);     
         
 
         // how much charecter is moving
         float move = Input.GetAxis ("Horizontal");
         
         //moving charecter ("rigidbody2D.velocity.y" keeps vertical velocity the same)
         rigidbody2D.velocity = new Vector2 (move * maxSpeed, rigidbody2D.velocity.y); 
         
         //links movement to void flip, && = and
         if (move > 0 && !facingRight)
             Flip ();
         else if (move < 0 && facingRight)
             Flip ();
     }
 
     
     void Update()
     {
                 
         // if jump button is pressed
         if (grounded && Input.GetButtonDown("Jump")) 
         {
                         rigidbody2D.AddForce(new Vector2(0, jumpForce));
         }
     }
         //flipping the world instead of creating left facing animation
     void Flip()
     {
         //!=not
         facingRight = !facingRight;
         Vector3 theScale = transform.localScale;
         theScale.x *= -1;
         transform.localScale = theScale; 
     }
 }

bullet code:

 using UnityEngine;
 using System.Collections;
 
 public class bulletScript : MonoBehaviour {
 
     public GameObject bulletPrefab;
 
     public float fireDelay = 0.25f;
     float cooldownTimer = 0;
 
     //update is called once per frame
     void Update(){
         cooldownTimer -= Time.deltaTime;
 
         if( Input.GetButtonDown ("Fire1") && cooldownTimer <= 0 ) {
                         // Shoot!
             Debug.Log ("Pew");
             cooldownTimer = fireDelay;
 
             Instantiate(bulletPrefab, transform.position, transform.rotation);
         }
     }
 }

bullet forward code:

using UnityEngine; using System.Collections;

public class MoveFforward : MonoBehaviour {

 float maxSpeed = 20f;
     
 // Update is called once per frame
 void Update () {

     Vector3 pos = transform.position;

     Vector3 velocity = new Vector3 (maxSpeed * Time.deltaTime, 0, 0);

     pos += transform.rotation * velocity;

     transform.position = pos;

 
 }

}

Any help is GREATLY appreciated.
