¿Cómo mostrar por pantalla el tiempo transcurrido en unity?

using UnityEngine;
using System.Collections;

public class PrintTime : MonoBehaviour
{
    private float startTime;
    
    void Start()
    {
        startTime = Time.time;
    }
    
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            float time = Time.time - startTime;
            print("Time: " + time);
        }
    }
}
