Mirror Edge, the game about under ground runner, has 14 level. You must control your character to avoid the obstruction. This runner game from EA had entered the Windows Phone Store for a while. It's exclusive for Nokia Lumia users, but it's not free.
But Now, Mirror Edge is opened to get install for free, exclusive for Nokia Lumia users. I download it with my Nokia Lumia 800 already. : )
You can download it here with your Lumia.
