The enemies in the TGS demo are simple and stupid and pose little threat, but one assumes that they quickly ramp up in ferocity and intelligence as the game progresses. You can move to evade foes, and the battle system is unconventional (which is where the tri-Ace influence comes into play). Your four party members seem to have different elemental affiliations, and attacks with spell projectiles that deal damage differently according to the target's orientation. The turn order system was surprisingly difficult for me to parse in the Japanese demo, but it's definitely not a typical RPG turn-based system.
