[玩耍]贪吃蛇

很久以前自己写着玩的，已经是上个学期的事情了，优化可能不是很好。但至少运行着不卡。。

用的Visual Studio2015，代码复制到别的编译器可能出问题。

成品地址：链接: http://pan.baidu.com/s/1nvKrL6T 密码: 57m5

实现的功能：蛇能跑能转弯能吃豆子（废话！）；按空格暂停，所以进游戏时如果发现蛇动不了，那就是你按了空格，再按一下就好；同时有三种豆子，白色的就是普通的豆子，红色的加速效果，蓝色的减速效果。不能穿墙；还有吃到豆子会有系统警告声，不要被吓到，因为这是我让游戏发出声音的最简单的办法了；

因为是当时学编程以来第一次做个成品，于是做了个极其花哨的开始界面，代码里很多都是花在界面上了，其实都是没用的代码

如果最大化窗口，会花屏，按一下R键可以稍微恢复一点界面；游戏会生成一个文件，用于储存最高分，当然完全没有加密什么的，打开就能看到你的所有成绩，你要篡改成99999也是没问题的。

还有完之前关掉输入法，不然界面显示会有问题，界面出问题了按R键刷新

还有，游戏的对话框按钮鼠标不支持，用左右或上下选择，enter确认
