It introduces some cool new mechanics like the weapon upgrade system, but overall it's a downgrade from Aria of Sorrow, the new villains are awful, the game is visually uglier, alot of the map layout design gets really annoying and some of its bosses are quite boring to fight.

Also please play the hack that removes all the touchscreen garbage, I would rate this game a 2/5 of how bad the touch magic seals are.
