Unity 2D Touch Controll via on screen button for Mobile

Hi.I have implemented touch controll over my game from diferent scripts I found on the web to be able to jump and move left/right via buttons on screens(im using GUI Textures i created).The problem is the script I ended up with is not very responsive and it just seems wierd. It all worked perfect on the computer when I was using Input.GetAxis horizonal but when I try via code it just does not have the same feel to it.Curently my problem is with Left/Right movement. Here is my code:

   void FixedUpdate()
 {
     grounded = Physics2D.OverlapCircle (groundCheck.position, groundRadius, whatIsGround);
     if(move < 0 && facingRight)
     {
         facingRight = !facingRight;
         Vector3 theScale = transform.localScale;
         theScale.x *= -1;
         transform.localScale = theScale;
     }
     if(move > 0 && !facingRight)
     {
         facingRight = !facingRight;
         Vector3 theScale = transform.localScale;
         theScale.x *= -1;
         transform.localScale = theScale;
     }
     // Check to see if the screen is being touched
     if (Input.touchCount > 0)
     {
         // Get the touch info
         Touch t = Input.GetTouch(0);
         
         // Did the touch action just begin?
         if (t.phase == TouchPhase.Began)
         {
             // Are we touching the right arrow?
             if (RIGHT.HitTest(t.position, Camera.main))
             {
                 move += 0.99f;
                 rigidbody2D.velocity = new Vector2(move * MaxSpeed,rigidbody2D.velocity.y);
                 anim.SetFloat("Speed",Mathf.Abs(move));
                 if(move > MaxSpeed)
                 {
                     move = MaxSpeed;
                 }
             }
             // Are we touching the left arrow?
             if (LEFT.HitTest(t.position, Camera.main))
             {
                 move -= 0.99f;
                 rigidbody2D.velocity = new Vector2(move * MaxSpeed,rigidbody2D.velocity.y);
                 anim.SetFloat("Speed",Mathf.Abs(move));
                 if(move > MaxSpeed)
                 {
                     move = MaxSpeed;
                 }
             }
             // Are we touching the jump button?
             if (UP.HitTest(t.position, Camera.main) && grounded)
             {
                     anim.SetBool("Ground",false);
                     anim.SetBool("Jumping",true);
                     rigidbody2D.AddForce(new Vector2(0,JumpForce));
             }
             if (DOWN.HitTest(t.position, Camera.main))
             {
                 anim.SetBool("Crouching",true);
             }

         }
         
         // Did the touch end?
         if (t.phase == TouchPhase.Ended)
         {
             anim.SetBool("Crouching",false);
             anim.SetBool("Jumping",false);
             anim.SetFloat("Speed",0);
             move = 0;
             // Stop all movement
             rigidbody2D.velocity = Vector2.zero;
         }
     }
     if(grounded && Input.GetKeyDown(KeyCode.Z))
     {
         move -= 10;
         rigidbody2D.velocity = Vector2.right * -5;
         anim.SetFloat("Speed",Mathf.Abs(-5));
     }
     if(grounded && Input.GetKeyUp(KeyCode.Z))
     {
         move = 0;
         anim.SetFloat("Speed",0);
     }
     if(grounded && Input.GetKeyDown(KeyCode.X))
     {
         move = 10;
         rigidbody2D.velocity = Vector2.right * 5;
         anim.SetFloat("Speed",Mathf.Abs(5));

     }
     if(grounded && Input.GetKeyUp(KeyCode.X))
     {
         move = 0;
         anim.SetFloat("Speed",0);
     }
     if(grounded && Input.GetKeyDown(KeyCode.Space))
     {
         anim.SetBool("Ground",false);
         anim.SetBool("Jumping",true);
         rigidbody2D.AddForce(new Vector2(0,JumpForce));
     }
     if(grounded && Input.GetKeyUp(KeyCode.Space))
     {
         anim.SetBool("Jumping",false);
     }
     if(grounded && Input.GetKeyDown(KeyCode.C))
     {
         anim.SetBool("Crouching",true);
     }
     if(grounded && Input.GetKeyUp(KeyCode.C))
     {
         anim.SetBool("Crouching",false);
     }
 }

I am using Z and X for left and right so I dont have to keep building versions for iPad to test.Hope you can help me.Thank you
