简单改进俄罗斯方块

对俄罗斯方块进行一部分优化：
参考地址：https://www.cnblogs.com/27dCnc/p/18568655
一、作业要求：从网上寻找一个项目或者小游戏，找出里面存在的不足之处，并且将它的不足之处优化。
二、运行环境：Windows
三、编译器：VSCODE
四、源代码*

App().main()

。 五、运行结果：[]()

六、代码优化：由于源代码无法显示得分以及用户用时情况，故优化一个计时以及得分牌子，来反映用户实时情况；

运行结果： 注意事项：得分和计时器显示在屏幕底部。 当新方块无法放置在网格顶部时，游戏结束，并在控制台打印“游戏结束”。 你可以截取运行中的游戏画面以查看视觉效果。 七、心得体会：对博客园有了一个初步认识，并且简单了解了一下部分小游戏的代码，并且体验了一把开发游戏权限的部分乐趣。
