Hello Yukia101. We really sorry for you having a bad experience and we'll be glad if you can tell us details about your problem.

I've had numerous problems, mainly with controls and cutscenes and battles not working. You pretty much can't use your cursor in battle since it never goes where you actually click it. The font choice is aweful to read and really bad for people with dyslexia. You can't go back in some menus so it traps you there until you either have to restart the game or you just waste your money in game. Subclasses don't have descriptions so you're just guessing what you're actually going into. The download didn't even have the full game in, I checked and it was just the demo. I really wanted to like this game, the characters are interesting but the game itself is just a nightmare, I honestly want a refund because this is unplayable.
