Porting a turn-based role-playing game to the iPhone is simple. Nailing the controls on a classic action RPG like Secret of Mana is another thing entirely. How did Square Enix do?
This is a pretty faithful recreation of the original classic on the iPhone (or iPad, in this case), and the controls are about as responsive as a virtual directional pad and button combo can get. There are certainly cheaper ways out there to experience Secret of Mana, but none are quite this convenient.
