haha, don't worry, you didn't made me feel stupid, I was just sharing the frustration I'm feeling with this game x.x.
However, I managed to beat chapter 4 and 4x yesterday doing everything right anyway. Luckily, everyone tried to kill Dashin but he dodged every single attack miracously when he was dying at that north part. My heart almost stopped but I'm glad its over. Did you find any part of this game more difficult than this one?
