Game broken

When attempting to access this at https://githubschool.github.io/github-games-IngoS11, 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 @IngoS11?

首先检查仓库的 GitHub Pages 设置，然后检查 issue 中提到的仓库 index.html 命名。https://githubschool.github.io/github-games-IngoS11 能够加载而不是返回 404 时，工作就完成了。
