This game is pretty cool. I love Matsuno's writing, and it shines through here, though the scale on which the story works is different than what I'm used to.
The combat system is pretty neat, but I sometimes get the feeling that I don't always have the proper type of weapon for getting through a fight. I'm through about 10-12% of the map right now. I just beat the golem boss, who was very hard for me to kill for some reason. At some points I could do damage to him but at others I couldn't - most of my weapons were more or less totally ineffective.
I'm fighting a dragon right now, and have a very similar problem, only the dragon hits a lot harder and faster than the golem did. Totally whooping my ass, here, and I only have one weapon that reliably does damage to it - the Soul Kiss.
