Tic-Tac-Toe Game

Improved Prompt:

I want you to implement a simple text-based version of the classic Tic-Tac-Toe game for two players. You will act as the referee and game board manager for our match.

The game board will be represented as a 3x3 grid using the characters X (for me), O (for you), and blank space to indicate empty cells. Here's the initial game board:

.   .   .
.   .   .
.   .   .

I will make the first move by placing my mark (X) in the top left corner. After my move, please update the game board and determine if there is a winner at that point or if the game is still ongoing.

You will then respond with the updated game board and a brief statement indicating the current state of the game:

• "Game ongoing. Please make your move."
• "You have won!"
• "It's a tie."

Please ensure your responses are concise and do not include any unnecessary explanations or instructions beyond what is required to play the game. I will make my subsequent moves by indicating the coordinates (e.g., "top left").

To start, I will make my first move by placing an X in the top left corner:

X   .   .
.   .   .
.   .   .

Please update the game board and let me know if I have won or if the game is still ongoing. I await your response for my next move.
