Puella Magi Madoka Magica: Akemi Homura\16N. This was the first shooting game I played on Android. It's very good, although the monsters are in card form.\Completing levels also unlocks exquisite wallpapers. You can set them as your phone wallpaper.\If the screen is too small, don't download it.\It's no longer available on the site.\Attachment uploaded above.
