"Collect Cubes" Like Player Movement and Rotation

Hi fellow game devs,
I am having difficulty recreating kinda same movement and rotation like the game "Collect Cubes"

So far I have wrote an script that somewhat works like the game but I haven't yet been able to reach the desired outcome. In Collect cubes the player moves and smoothly rotates along the user touch swipe/drag direction and the smooth transition don't mess with collision or other physics properties.

Here is what I have done so far..

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using DG.Tweening;
5.  
6. public class PlayerController : MonoBehaviour
7. {
8.     private Rigidbody rigidBody;
9.     private Vector3 screenPoint;
10.     private Vector3 offset;
11.     private Vector2 startPos;
12.     private bool isSwiping;
13.     private Vector3 direction;
14.     private Vector2 currentSwipeDelta;
15.     private Vector2 previousSwipeDelta;
16.     private Vector3 moveDirection;
17.     public float movementSpeed;
18.     private Vector3 newDir;
19.     private float swipeStartTime;
20.     private float swipeEndTime;
21.     private float swipeInterval;
22.  
23.     // Start is called before the first frame update
24.     void Start()
25.     {
26.         rigidBody = GetComponent<Rigidbody>();
27.     }
28.  
29.     // Update is called once per frame
30.     void Update()
31.     {
32.         PlayerInput();
33.     }
34.  
35.     private void PlayerInput()
36.     {
37.         if (Input.GetMouseButtonDown(0))
38.         {
39.             startPos = Input.mousePosition;
40.             GameManager.Instance.StartGame();
41.         }
42.  
43.         if (Input.GetMouseButton(0))
44.         {
45.             isSwiping = true;
46.             direction = Input.mousePosition - (Vector3)startPos;
47.             direction = Vector3.Normalize(direction);
48.         }
49.  
50.         if (Input.GetMouseButtonUp(0))
51.         {
52.             isSwiping = false;
53.             direction = Vector2.zero;
54.         }
55.  
56.         currentSwipeDelta = Vector2.zero;
57.  
58.         if (isSwiping)
59.         {
60.             currentSwipeDelta = Input.mousePosition - (Vector3)startPos;
61.         }
62.  
63.         transform.localPosition = new Vector3(Mathf.Clamp(transform.localPosition.x, -5.9f, 5.9f), transform.position.y, Mathf.Clamp(transform.localPosition.z, -1f, 21f));
64.     }
65.  
66.     private void FixedUpdate()
67.     {
68.         if (currentSwipeDelta.magnitude > 30)
69.         {
70.             moveDirection.x = direction.x;
71.             moveDirection.z = direction.y;
72.             moveDirection.y = 0f;
73.  
74.             // Rotation
75.             Quaternion newRotation = Quaternion.LookRotation(moveDirection);
76.             Quaternion deltaRotation = Quaternion.Euler(new Vector3(0f, 360f, 0f) * Time.deltaTime);
77.             rigidBody.MoveRotation(newRotation * deltaRotation);
78.  
79.             // Move
80.             rigidBody.velocity = moveDirection * movementSpeed;
81.         }
82.     }
83. }
84.  

What I am doing wrong and what needs to be done to achive the smooth movement like Collect Cubes?
Any help will be appreciated. Thanks in advance ​
