CodeinGame Power of Thor level 2 wont work

I was solving a problem in CodeinGame where i have to take Thor to the light lightx & lightY is the light position & thorx & thory is the position of thor.& initiaTX , initiaTX are starting thor position but it fails some test cases on the site for eg : if initial pos is (5,4) it passes Log but if initial pos is (31,17) it fails Log

My code

        string[] inputs = Console.ReadLine().Split(' ');
    int lightX = int.Parse(inputs[0]); // the X position of the light of power
    int lightY = int.Parse(inputs[1]); // the Y position of the light of power
    int initialTX = int.Parse(inputs[2]); // Thor's starting X position
    int initialTY = int.Parse(inputs[3]); // Thor's starting Y position

    // game loop

    int thorx=initialTX;
    int thory=initialTY;

    string directionX, directionY;

    while (true)
    {
        int remainingTurns = int.Parse(Console.ReadLine()); // The remaining amount of turns Thor can move. Do not remove this line.

        // Write an action using Console.WriteLine()
        // To debug: Console.Error.WriteLine("Debug messages...");

        if (thorx>lightX)
        {
            directionX="W";
            thorx=-1;
            Console.WriteLine("W");
        }
        else if (thorx<lightX)
        {
            directionX="E";
            thorx=+1;
            Console.WriteLine("E");
        }
        else
        {
            if (thory>lightY)
            {
                directionY="N";    
                thory=-1;
                Console.WriteLine("N");
            }
            else if (thory<lightY)
            {
                directionY="S";
                thorx=+1;
                Console.WriteLine("S");
            }
        }
