Player making a 360° looping, camera not following

Hi people!

I'm in trouble again, I made a level where the player is constantly accelerating to its local forward, and we guide him like a missile through obstacles (a little like in Rayman 3 if you remember).

Problem is, I want to make more than 90° loops, and that's where the camera doesn't follow.

Actually past 90°, camera AND player rotate 180° around the forward axis of the player, so its "head up and feet down". But I want the player to keep going "feet up and head down", because its a looping.

I think it's in the Cam Script in the Update. Made several changes but can't find the fix.

Here's the Camera script :

 {    
     public Transform lookAt;
     public Transform camTransform;
 
     private Camera cam;
 
     public float distance = 8.0f;
     public float currentX = -160.0f;   //starting position
     public float currentY = 10.0f;   //starting position
     public float sensitivityX = 4.0f;
     public float sensitivityY = 1.0f;
 
     private void Start()
     {
         camTransform = transform;
         cam = Camera.main;
         transform.forward = Camera.main.transform.forward;
     }

 
  I GUESS THE PROBLEM COMES FROM HERE - Update !
     private void Update()
     {
         currentX += Input.GetAxis("Mouse X");
         currentY -= Input.GetAxis("Mouse Y");
     }
 
     public float heighT = 6;
 
     private void LateUpdate()
     {
         Vector3 height = new Vector3(0, heighT, 0);
         Vector3 dir = new Vector3(0, 0, -distance);
         Quaternion rotation = Quaternion.Euler(currentY, currentX, 0);
         camTransform.position = lookAt.position + rotation * dir;
         camTransform.LookAt(lookAt.position + height);
     }
 }

The controls script :

 {
     public float speed = 10.0f;
     public Rigidbody rb;
     public float Forw = 1F;
     public float Cam = 50F;
     public Camera mainCamera;
 
     void Start()
     {
         rb = GetComponent<Rigidbody>();
     }
 
     void Update()
     {
         transform.forward = Camera.main.transform.forward;
         if (Forw <= 80) Forw += 0.01F;    // to accelerate the player see further.
         mainCamera.GetComponent<Camera>().fieldOfView = Cam;
         if (Cam<=90) Cam += 0.01F;    // modifying the field of view.
     }
 
     void FixedUpdate()
     {
         rb.velocity = transform.forward * Forw;
     }
 }

That kind of level setting
