虽然本人一直是个免费的游戏测试员（/手动滑稽），但一直有着一个游戏架构师的梦想。正如马爸爸所说，梦想还是要有的，万一实现了呢？
这些天放寒假，有些空闲时间，就想着做一个简单的游戏机。能达到小时候十几块钱买的那种小霸王的功能就差不多了（有贪吃蛇，赛车小游戏，俄罗斯方块，雷霆战机，坦克大战，2048，拼图等），好吧，原谅我有些浮夸风（/手动斜眼）。。。
这不，下面是我这两天抠出来的一个最简单的贪吃蛇小游戏，姑且叫它“大大维的贪吃蛇v1”吧！！！
游戏功能比较简单，后续还需要完善。先将代码在这保存一份，日后看看，也是一件挺有意思的事情吧！！！
/**--------------------------------------------------**/
/**名称：大大维的贪吃蛇v1 日期:2017/1/22**/
/**描述：实现了贪吃蛇的基本功能，可以调节游戏难度，**/
/**做了一个简单的用户界面 **/
/**存在的问题：由于使用了全局数组存贮，因此对Space **/
/**类的封装有些欠缺；由于使用了全局刷新，游戏运行中**/
/**会出现闪屏现象，游戏难度越高，闪动越严重；不能够**/
/**存储玩家的游戏记录，由于不是图形化界面，用户界面**/
/**较丑;不能改变游戏的地图大小 **/
/**笔者会在后续版本逐步完善这些问题!!! **/
