URL in description and README broken

The URL in the repository description and the one in the README are pointing to githubschool's copy of the game instead of yours.

Please fix both so they point to your copy of the game at https://githubschool.github.io/github-games-nereus1/

Open README and inspect the repository description, then compare both URLs with the target URL in the issue. Update both references to point to the repository's GitHub Pages game URL and verify that the README link and description link resolve correctly.
