This a game complicated to recommend, but I decided recommend it for his history.

"So give meaning to the tears"
This is the main focus of history, simple enemies, bosses, villains, party members and even sceneries, all fits in this phrase.
The script consists in reveal the history very slow, but always leaving you with curious.

Out of history, the game runs good, without issues with performance or bugs.

but, the bad side is the tedious.

Very repetitive, always with same simple combo again and again, all maps is very similar with each one, Have a lot of recycled enemies.
and the worse, the Level Design of each map is... torturously tedious with great labyrinths without reasons, and for end, if you ignore almost all normal enemies, you beat the game without any effort.

The game brace in the history and characters, if you pass for the tedious, you find a good game with good story.
or if you consider the bad things as "part of ambient" of the game, what did I do, enduring the tedious part and I found a game that I never forget.

- Rei room is one of the best hub that I see (I spent a lot of time only seeing Rei interacting with his room) and Kuon best girl -
