Game broken

When attempting to access this at https://githubschool.github.io/github-games-jmm99, 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 @jmm99?

Start in the repository Settings > Pages area and check the deployment source for the master branch. Reload https://githubschool.github.io/github-games-jmm99 after the setting is enabled; done means the site no longer returns a 404.
