 However , GameBrink.Com felt that the gameplay , user @-@ friendly even to non @-@ Japanese players , consists of too much repetitive button mashing despite featuring characters with different abilities . The Code Extension mode was considered imperfectly implemented , seeming as if it were " tacked on [ … ] late in development " , being totally optional yet difficult not to use to survive in the later missions . Calling the gameplay " shallow " , the site stated that " the soundtrack would probably be a better purchase than the actual game " . On its part , Siliconera noted that while the gameplay may seem complex for using every button on the controller , thirty minutes were enough to grasp how to play the game . The site felt the missions were designed with good pacing and replayability value , but added that hardcore role @-@ playing game fans could dislike the lack of exploration , puzzle , and standard role @-@ playing game principles .
