Just wanted to say that it was a great game. I've finished the story, but in a way, it has just started...
My first impression is the battle music. It was catchy enough that playing it in hundreds of battles never bored me. Boss musics were also incredibly climactic.
The first boss was quite challenging, but little did I know there was a lot more in store. Many boss-specific gimmicks are so satisfying once I figured it out. The enrage mechanic blended incredibly well with the battle system.
The fight that was supposed to be what the characters were chasing after as an end goal... I thought that that would be the final battle, but it turns out that true to the synopsis, "they've been chasing the wrong target, and their final battle is about to become anything but". After that, it turns out the worlds now open up and there are much to be explored.
The designed items are incredibly well-suited for battles; the item that basically shortened the first phase of the first boss against an inevitable death actually had uses in similar ways much later. I had to learn the ways I can take advantage of any loots I picked up. (But then in the very last part, it turned out the very loot that must always be examined contains something... special.)
It was a great place to spend time in, thanks for the feast!
