Problem with 3D mobile diagonal swipe controls

I've been trying out diagonal swipe controls on a 3D mobile game where the player moves North East, North West, South East, and South West depending on the diagonal direction the player swipes

(The main camera is set so that it looks at the plane that the playerobject is on from a diagonal of the plane instead of the side).

But When I test the program on the Phone, not matter which direction I swipe, the player will only travel South West.

 using System.Collections.Generic;
 using UnityEngine;
 
 public class MobileControls : MonoBehaviour
 {
     Vector3 initTouchPos;
 
     private void FixedUpdate()
     {
         restart:
         foreach (Touch touch in Input.touches)
         {
 
             if (touch.phase == TouchPhase.Began)// detects finger on screen
             {
                 initTouchPos = touch.position;// sets initial finger position
             }
                 if (touch.phase != TouchPhase.Ended && touch.phase != TouchPhase.Canceled)
                  {
                     if (touch.phase == TouchPhase.Moved)
                     {
                         float initX = initTouchPos.x, initY = initTouchPos.y;
                         Vector3 touchDeltaPos = Input.GetTouch(0).deltaPosition;// gets coordinatesof delta position
                         float deltaX = touchDeltaPos.x, deltaY = touchDeltaPos.y;// sets sets x & y position of delta touch to "deltaX" & "deltaY"
                         
                         
 
                         if (deltaX < initX && deltaY < initY)//SW
                         {
                         transform.Translate(Vector3.left);
                         }
                         else if (deltaX > initX && deltaY < initY)//SE
                         {
                         transform.Translate(Vector3.back);
                         }
                         else if (deltaX < initX && deltaY > initY)//NW
                         {
                         transform.Translate(Vector3.forward);
                         }
                         else if (deltaX > initX && deltaY > initY)//NE
                         {
                         transform.Translate(Vector3.right);
                         }
                     }
                 else  if (touch.phase == TouchPhase.Ended || touch.phase == TouchPhase.Canceled)// detects end of touch
                 {
                     goto restart;// restarts touch detection fron "restart"
                     
                 }
             }
         }
     }
