My Progress Update

[Horusofoz]

Here’s what I’ve got at the conclusion of Lecture 27. Using previous C# knowledge made this a lot harder than it should have been. I’ll be more conservative going forward to keep to the steps shown in the lectures.

using UnityEngine;

public class Hacker : MonoBehaviour {

    // Game state
    int level;
    enum Screen { MainMenu, Password, GameOver };

    const int PasswordAttemptsStart = 3;

    List<string> level1passwords = new List<string>();
