It has no mayor problem running on iphone, its great for play in any free time you got. It has a wonderfull story that immerse you and doesnt let you go , i have found myself playing for hours until my battery dies. You can choose your 3 main character to play, every one of them has a special kind of magic being each one of there best for diferent monster, the game challenge you to change your strategy in some bosses that are really hard and can drain your life very quickly. The only problem I could find its that sometimes you get stuck when running but this happen only occasionally.
Sometimes you found yourself not knowing what to do but they are always clues that help you trough the game. Its a wonderfull experience to play this game, if you have played this when you where a kid it will bring good memories
All an all its a must in your iphone, although is a bit expensive its worth it
