纯WINDOWS API的C++2D小游戏Subterra(目前还未开发，实时更新)

运行方式：

• Visual Studio (请拥有“使用 C++ 的桌面开发”工作负载)
  下载方式：https://visualstudio.microsoft.com/zh-hans/dowloads/
  （若上述方法不行，请在 Microsoft Store 内尝试搜索 Visual Studio Community 并下载）
  请启动VS（建议使用VS2026）：创建新项目> Windows 桌面应用程序> 输入项目名称> 创建
  右键“源代码”> 新建> main.cpp

main.cpp源代码
