If Else语句逻辑

我正在做一个基于文本的小游戏，我的一个if/else语句没有给我预期的结果。当用户输掉游戏时，它会立即跳转到"Game Over!"它应该说monsterName +"已经打败你了!"然后跳转到游戏结束。

你们能帮我指出我的逻辑错误吗?

// Main Game Loop
while (playerHealth > 0 && monsterHealth > 0)
{
    bool playerAct = askAction();
    if (playerAct == true)// User attacks
    {
        monsterHealth = monsterHealth - playerAtk;
        if (monsterHealth < 0)
        {
            Console.WriteLine(monsterName + " falls to the ground, defeated. Congradulation, " + name + "!");
        }
        else
        {
            Console.WriteLine(monsterName + " takes a mighty swing back at you!");
            playerHealth = playerHealth - monsterAtk;
        }
    }                
    else// User defends
    {
        playerHealth = playerHealth - defendAtk;
        if (playerHealth < 0)
        {
            Console.WriteLine(monsterName + " has defeated you!");
        }
        else
        {
            Console.WriteLine(monsterName + " swings at you. It glances off your defenses.");
        }
    }               
}
// End Game
Console.WriteLine("Game Over!");
Console.ReadLine();            

我想那是相关的代码，但为了以防万一，这里是整个程序。

namespace textBasedGame
{
    class Program
    {
        static void Main(string[] args)
        {
        //Variables
        string name;
        string monsterName;
        int playerAtk = 5;
        int monsterAtk = 2;
        int defendAtk = 1;
        int playerHealth = 2;
        int monsterHealth = 3;
        // Gathers information from the user
        Console.WriteLine("What is your name?");
        name = Console.ReadLine();
        Console.WriteLine("What is your enemies name?");
        monsterName = Console.ReadLine();
        //Story Intro
        Console.WriteLine("You are hunting in the swamp and in the darkness of the overgrowth you see a movement.");
        Console.WriteLine("You creep closer to the silouette.");
        Console.WriteLine("A little closer....");
        Console.WriteLine("It looks familiar....");
        Console.WriteLine("It is " + monsterName + "!!!");
        Console.WriteLine("Now is your chance!");
        // Main Game Loop
        while (playerHealth > 0 && monsterHealth > 0)
        {
            bool playerAct = askAction();
            if (playerAct == true)// User attacks
            {
                monsterHealth = monsterHealth - playerAtk;
                if (monsterHealth < 0)
                {
                    Console.WriteLine(monsterName + " falls to the ground, defeated. Congradulation, " + name + "!");
                }
                else
                {
                    Console.WriteLine(monsterName + " takes a mighty swing back at you!");
                    playerHealth = playerHealth - monsterAtk;
                }
            }                
            else// User defends
            {
                playerHealth = playerHealth - defendAtk;
                if (playerHealth < 0)
                {
                    Console.WriteLine(monsterName + " has defeated you!");
                }
                else
                {
                    Console.WriteLine(monsterName + " swings at you. It glances off your defenses.");
                }
            }               
        }
        // End Game
        Console.WriteLine("Game Over!");
        Console.ReadLine();            
    }
    static bool askAction()//Displays HP and asks for user action. Returns true or false
    {
        bool move;
        Console.WriteLine("What would you like to do?(type: attack or defend)");
        string playerAction = Console.ReadLine();
        if (playerAction == "attack")
        {
            return move = true;
        }
        else
        {
            return move = false;
        }
    }
}
