Fliping a sprite

So im creating a 2d cursor shooter, and the players arm/gun rotates towards the cursor, but it look’s really odd because the Character itself does not flip towards the mouse (i dont want it rotating towards it, just a simple left/right flip)

using UnityEngine;
using System.Collections;

public class Spriteflip : MonoBehaviour {

	public int rotationOffset = 90;
	public Transform target;
	Camera camera;
	private Transform playerScreenPoint= Camera.main.WorldToScreenPoint(player.transform.position);

	void Start() {
		camera = GetComponent<Camera>();

	// Update is called once per frame
	void  Update (){
		if(mouse.x < playerScreenPoint.x) {
		} else {

		private void Flip()
			// Switch the way the player is labelled as facing.
			m_FacingRight = !m_FacingRight;
			// Multiply the player's x local scale by -1.
			Vector3 theScale = playerGraphics.localScale;
			theScale.x *= -1;
			playerGraphics.localScale = theScale;

To flip a sprite, just set its x or y axis to -1
