Upon opening the game, a window will appear instructing you to enter the code. Keep in mind that the aforementioned code is essentially pre-filled, with the first on the left and the last two letters on the right. Your task is to simply input the remaining characters in lowercase beneath. Pay close attention to the details in these images.

Do not disclose your code to others; it is unique and intended solely for your use!
