I've been playing Chrono Trigger two days ago. I'm stuck in this game, part of "The End of Time." I must go to the door behind the old man, then there's a monster about magic in this game, start from the door of that monster's room, I ran/walked around like the circle clockwise, talk to that monster and nothing, so I'm stuck. Since I'm stuck in this game, how do I do this from above my post? Any help?
