The game is amazing! There are cute and handsome characters, and it isn't laggy. Though, the only problem is the gameplay, it isn't really that nice, its a bit laggy whenever I tap the notes, but it doesn't really bother me. The game is amazing overall and I BADLY hope it gets a global version soon, its just that its lacking something, probably better gameplay and the cards need more details.
EDIT: Yes, the game is working smoothly, all I needed to do was to just set the background to favorite card so that the gameplay isn't laggy anymore (it is still a little bit laggy but not as much.) I LOVE SENGOKU A LIVE!!! (and Nobunga)
