To elaborate this is how I felt about the demo:
-I like the Metroidvania battle system where you get enemies and use them as attacks. This means in concept, lots of variety in attacks, spells, other things like the Metroidvania's that let you steal souls.
-I like the graphics and art style
-I really don't like that you are forced to play it with both characters
-I don't like the map movement. It felt like a bad RE/Onimusha game.
-I don't like how the level in the demo just felt like a bunch of same looking areas with encounters along the way
-I don't like that there's lots of text but no voice. Feels cheap
-I don't like the cheezy English dub and lack of Japanese voice acting for the Japanese version
I'll probably still play it one day. But it's sitting with White Knight Story in my pile of JPN PS3 games I bought because they looked cool, heard they were boring or had severe flaws, and lost interest in actually playing them.
