Tic Tac Toe

Game Overview

Tic-Tac-Toe is a lightweight, cross-platform game built with Godot 4.x. It supports three modes:
- PvP (local two players)
- PvE (play against an adjustable AI)
- Online (host or join a 1v1 match over LAN / internet using ENet)

Unique Game Mechanic

Players are limited to 3 pieces on the board at a time. When placing a 4th piece, the oldest piece is automatically removed. This prevents traditional draws.

Key features
- Three play modes: PvP, PvE (AI), Online
- Five AI strategies / three difficulties
- Undo support (local modes)
- Rematch flow: both players must agree before a restart
- Clear UI notifications for connection, rematch, and disconnect events

How to play
- X always goes first (Host in online mode plays as X)
- Click an empty square to place your piece
- If a player reaches three in a row they win; winner dialog appears
- In online matches, only the player whose turn it is can place pieces

Multiplayer
- Lobby size is restricted to 2 players (host + 1 client). Attempts to join a full lobby will be refused and show a readable error.
- Rematch requires both players to click "Play Again" in the Game Over dialog. The dialog will show how many players are ready (1/2, 2/2) and indicate if the opponent disconnected.
