  Welcome to the community, @abysan.

  You can do this with a custom script that moves characters in a 2D grid. For a game like the one above, you'll first want to make use of Unity's Tilemap system to create your 2D scene.

  Then, set the AC Scene Manager's Pathfinding method to A Star 2D, which uses a grid system for navigation.

  Create a Tilemap specifically for the floor, and attach a Tilemap Collider (with "Is Trigger" checked) and AC's Navigation Mesh component. Reduce the Cell size so that it matches the tiles, and assign this as the Scene Manager's Default NavMesh.

  There's a few elements at play with the above, so share screenshots if you get stuck and I'll point you in the right direction.

  Once done, it's then a case of setting your Settings Manager's Movement method to None, and attaching a simple script like the one below (GridMovement.cs) to your Player character. Keep the Player in the scene and fill in their Inspector with a reference to the "floor" Tilemap created earlier:

  using UnityEngine;
  using UnityEngine.Tilemaps;
  using AC;
  
  public class GridMovement : MonoBehaviour
  {
  
      public Tilemap tilemap;
      private Grid grid;
      private Char acCharacter;
  
  
      private void Start ()
      {
          acCharacter = GetComponent <Char> ();
          grid = tilemap.transform.parent.GetComponentInParent<Grid> ();
      }
  
      void Update()
      {
          if (!KickStarter.stateHandler.IsInGameplay () 
              || (!acCharacter.IsPlayer || KickStarter.settingsManager.movementMethod == MovementMethod.PointAndClick)
              || acCharacter.IsMovingAlongPath ())
          {
              return;
          }
  
          if (acCharacter.IsPathfinding ()) return;
  
          Vector2 moveInput = new Vector2 (KickStarter.playerInput.InputGetAxis ("Horizontal"), KickStarter.playerInput.InputGetAxis ("Vertical"));
          if (moveInput.sqrMagnitude < 0.01f) return;
  
          float cellWidth = grid.cellSize.x;
          float cellHeight = grid.cellSize.y;
  
          float moveX = moveInput.x == 0 ? 0f : moveInput.x > 0f ? 1f : -1f;
          float moveY = moveInput.y == 0 ? 0f : moveInput.y > 0f ? 1f : -1f;
  
          Vector3 targetWorld = acCharacter.transform.position + new Vector3 (moveX * cellWidth, moveY * cellHeight, 0f);
          Vector3Int cellPosition = tilemap.WorldToCell (targetWorld);
  
          bool hasTile = tilemap.GetTile (cellPosition);
          if (!hasTile) return;
  
          Vector3 cellWorld = tilemap.CellToWorld (cellPosition);
          cellWorld += new Vector3 (cellWidth * 0.5f, cellHeight * 0.5f);
  
          acCharacter.MoveToPoint (cellWorld);
      }
  
  }

  This is very useful and super answer, not just for me. I hope in the future other people will be able to use it well ^^
