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-imuntyan

Check the repository description and README, where the incorrect game URLs are mentioned. Update both links to https://githubschool.github.io/github-games-imuntyan, then verify that the description and README point to that URL.
