Cortney "Alethea" Stone writes "The battle system is a little like the one in Final Fantasy XII. Enemies freely roam the area, and you can run up to them and attack. You control one character at a time, and it can be whichever party member you choose. You're also able to transform into the White Knight and take on much larger enemies.
Overall, my impression was quite positive. I found the controls for the party as well as the ones for the White Knight to be quite user-friendly. Unlike with Kingdom Hearts 358/2 Days, White Knight Chronicles was working with me instead of against me."
