# Python Pac-Man 遊戲

以下是一個使用 Pygame 庫實現的簡單 Pac-Man 遊戲。這個遊戲包含一個黃色小球(Pac-Man)在迷宮中移動，玩家可以使用鍵盤方向鍵控制方向。

## 遊戲說明

1. *控制方式*：
   - 使用鍵盤方向鍵（上、下、左、右）控制 Pac-Man 移動

2. *遊戲元素*：
   - 黃色圓形角色 (Pac-Man)
   - 藍色迷宮牆壁
   - 白色小點作為食物

3. *功能特點*：
   - Pac-Man 有動態的嘴巴開合動畫
   - 碰撞檢測防止穿牆
   - 方向鍵預輸入功能（可以提前按下方向鍵，當可以轉向時會自動轉向）

## 運行要求

需要安裝 Pygame 庫：

pip install pygame


這個遊戲是一個基本實現，你可以進一步擴展它，例如添加鬼魂敵人、分數系統、關卡設計等來增強遊戲性。
