The game has an interesting premise, a killer soundtrack, and a neat combat system where you time your attacks to try and set up combos and disrupt the enemies. That said, they don't execute this well at all, the game never throws a situation at you where you have to use this system to its full effect, and then the game throws a lot of trash encounters at you. That combined with incredibly weak dungeon design really undermines the game.
Appearance wise it's pretty obvious that this is a vita port, it's not bad on the eyes, but it's not good on the eyes either
This is very much a function of whether you can suffer through the gameplay to enjoy the pretty gud story.
