前言
人类建造迷宫已有5000年的历史。在世界的不同文化发展时期，这些奇特的建筑物始终吸引人们沿着弯弯曲曲、困难重重的小路吃力地行走，寻找真相。迷宫类小游戏应运而生。在游戏中，迷宫被表现为冒险舞台里，藏有各式各样奇妙与谜题或宝藏的危险区域。型态有洞窟、人工建筑物、怪物巢穴、密林或山路等。迷宫内有恶徒或凶猛的生物（真实存在或想像物体都有）徘徊，其中可能会有陷阱、不明设施、遗迹等。
《复杂迷宫》游戏是用java语言实现，采用了swing技术进行了界面化处理，设计思路用了面向对象思想。
主要需求
方向键控制移动，角色走出迷宫，游戏胜利。增加游戏难度和增加随机地图。
主要设计
构建游戏地图面板
设定迷宫地图，包含可走的通道，不可走的墙体，还有出口位置
键盘的上下左右按键，来控制角色的移动
角色移动的算法，通道可走，遇到墙体不可走
走到终点，有成功通关的提示。
增加游戏的难度选择，难度1，难度2和难度3
每次生成的地图是随机的
地图大小可选择，迷宫的长在10-45之间，宽在10-90之间
增加撞墙的音乐效果
功能截图
游戏开始页面
生成难度1，10*10的迷宫地图
随机地图：生成难度1，10*10的迷宫地图
生成难度2，30*30的迷宫地图
生成难度3，90*45的迷宫地图
成功过关-效果
