！！注意！！

此版本有很多 bug，如果你想要更稳定的体验，请使用上一个稳定版本 0.2.1，链接在下面。

MemoryGame v0.2.1
C++ & MC 讨论团

真的写不动了qwq...

新增：

• 配置文件，用于存储设置、用户信息等内容，存储在 MemoryGame.json 中
• • 需在 json.hpp 的 GitHub 仓库下载 json.hpp （点我直接下载），放到与这个cpp文件同一个目录后使用新版本
• • 如果下载速度很慢，可以考虑使用 $\text{Magic}$
• 日志系统，不过目前是坏的

已知bug：

• 修改难度数值界面无法退出（应该是输入 0 退出）
• 日志系统是坏的
• 将 COUNTDOWN_BASE 变量初始值设置为 0，会在计算倒计时的时候发生 0xC0000094 错误（除以 0）
• 不支持除 Windows 以外的任何平台（因为使用了 windows.h，以后会考虑兼容，但那就是以后的事了）

如果有其他 bug 请到我的 Luogu 主页或者 acgo 上私信我反馈，我会尽快修复。

如果代码中文可以显示但是控制台无法显示，请将代码最前面的 system("chcp 65001") 删除，即可正常游玩
