Finally: the combat system is bad. Very bad. You can't rely on any tactics, the only way to reliably fight is to be overleveled. The perfect example is the demon in syphon mode. She can heal ... sometimes. You want her to drain an enemy to heal herself? Too bad, she drain the mp. You want her to heal Viviane? Too bad she restored the non-existent MP.
I don't know why you chose combat like that, but having no control and very different outputs, doesn't make the game fun or interesting.
The game look good and promising, but please add a way to control your party. Either remove entirely the random attacks system or add a way to choose the attacks (be it limited number per fight or unlimited)
