How to fix rotation while moving character

Hi, I made a challenge for myself. Within 2 weeks I should create a small game. Here is my first problem. I can't fix the rotation while I'm moving my character. The character acts like crazy. Pls help. Here is my code. Sorry for Eng.

 public float horizontalSpeed = 1;
 public float verticalSpeed = 1;
 public float rotatingSpeed = 13;
 
   

 private void Update()
 {
     if (Input.GetKey(KeyCode.Mouse0))
     {
         
         float h = horizontalSpeed * Input.GetAxis("Mouse X");
         float v = verticalSpeed * Input.GetAxis("Mouse Y");
         transform.Translate(h, 0, v);

         float hs = rotatingSpeed * Input.GetAxis("Mouse X");
         transform.Rotate(0, hs, 0);
         
     }
 }

}
