Game broken

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

Open the repository settings and inspect the GitHub Pages configuration, focusing on whether it is enabled from master as requested in the first bullet. Then revisit https://githubschool.github.io/github-games-imrandyk/ and confirm it no longer returns a 404. The issue also mentions inde.html, but the requested change is the Pages setting.
