The game features a seemingly endless grind in a series of gigantic dungeons where everything, including the dungeon itself, tries extremely hard to murder you. The encounters are highly challenging, the grinding process is tiresome, and the game system is hard to grasp. In addition, the game expects you to level a couple dozen of characters to max level, MULTIPLE TIMES, before you have any chance defeating any of the hidden bosses. And yes, you need to defeat each and every one of them in order to advance to the true end of the story.

But in the end, the plot makes everything worth it.
