Python打字小游戏《Alphabet Zoo》

游戏说明：（macOS平台下开发调试）游戏视频

点击屏幕中间的Play按钮。屏幕顶部产生下落的随机字母，敲击键盘上相应的键对应字母消失。字母生成和坠落的速度随着时间由慢变快，难度逐渐增大。坠落到屏幕最下方的字母超过十个，游戏结束。

游戏设置了记分系统，敲对一个键记50分，敲错扣50分。游戏最高分和当前得分分别显示在顶端中间和右边。

另外还添加了背景音乐，敲对、敲错以及字母下落到底部的时候有不同的音效。

由于时间仓促，没有添加注释，这是程序的缺陷。如果以后有时间，会补充完善。

程序用到的字母图案和声音文件无法上传展示。

东抄西问的成果，感谢提供帮助的人。
