2d character controller for platformer with touch or mouse input?

I guess I will answer this one myself. The most helpful information I have found on character controllers was Unity Live training video about Robot character animation. But it was just classic platformer type of controls. Also i found this helpful thread: Point to click movement in a 2d game

// Define a variable vector for the position you will want the object to move to. Vector3 wantedPos;

// Get the position of the mouse click. Vector3 mousePos = Input.mousePosition;

// Transmogrify the mouse coordinates to the coordinate system of your game space. wantedPos = Camera.main.ScreenToWorldPoint (new Vector3 (mousePos.x, mousePos.y, 1f));

// Determine the vector from your desired (ending) position and the game objects current position. Vector3 relativePos = wantedPos - transform.position ;

// Move your game object using a rigid body force to get it moving in the right direction. transform.rigidbody2D.AddForce(relativePos.normalized * 40f);

Tried to merge these two approaches for my case and wrote this piece of code(it is a C# script to attach to the character):

 using UnityEngine;
 using System.Collections;
 
 public class Indiana2 : MonoBehaviour {
     
     public Vector3 target; // The point user picks for the character to follow
     public bool facingRight = false; // Check where the character is facing
     private int move=0; // Movement direction
     private float maxSpeed = 5f; // Speed of character movement
     private Animator anim; // Reference to the animator
     
     
     // Use this for initialization
     void Start () 
     {
         anim = GetComponent<Animator> ();
     }
 
     void FixedUpdate()
     {
         // Obtaining target point user clicked on screen
         if (Input.GetMouseButton (0))     
         {
             // After user has clicked left mouse button recording mouse position
             Vector3 mousePos = Input.mousePosition;
             // Converting mouse position into coordinate system connected to the camera.
             target = Camera.main.ScreenToWorldPoint (new Vector3 (mousePos.x, mousePos.y, 1f));
 
             // Set movement direction depending on target point
             if (target.x < transform.position.x)
                 move = -1;
             else if (target.x> transform.position.x)
                 move = 1;
             Debug.Log (move);
         }
                 
         // Flip the character if nessessary
         if (move ==1 && ! facingRight)
             Flip ();
         if (move == -1 && facingRight)
             Flip();
         
         // check if arrived to target point
         if (Mathf.Abs (target.x - transform.position.x) < 0.2f)     
         {
             move = 0;
         }
         
         anim.SetInteger ("Movement", Mathf.Abs(move));
         
         // apply velocity to actually make character move
         rigidbody2D.velocity = new Vector2 (move * maxSpeed, rigidbody2D.velocity.y);
         
         
     }
     
     
     void Flip()
     {
         Debug.Log ("In Flip");
         facingRight = !facingRight;
         Vector3 theScale = transform.localScale;
         theScale.x *= -1;
         transform.localScale = theScale;
     }
 }
