Game broken

When attempting to access this at https://githubschool.github.io/github-games-Mingjing56/, I am getting a 404. This could be caused by a couple things:

- GitHub pages needs to be enabled on master. You can fix this in the repository settings.
- the index.html file is incorrectly named inde.html. We will fix this together in class.

Can you please fix the first bullet @Mingjing56?

打开仓库的 GitHub Pages 设置，检查 master 上是否已启用 Pages；该 issue 明确要求先处理这一条。验证已部署的 URL 能否加载，同时注意，单独的 inde.html/index.html 项被描述为课堂作业。
