I agree with The_JSTREET. The storyline was totally lackluster. The gameplay kept me interested though because you can actively kill everything on the map without transitioning to some lame "we're all having a battle now" map.
Another thing that weirded me out was that little sprite thing was a dude. I totally thought that it would be a girl, because it just looked like a girl to me. That was disappointing.
I never beat the game either. I got to the big Mana Beast at the end and it totally annihilated me. I think you're supposed to use some special item to fight it, but it would never work for me. I didn't really care too much after a while, because the story never really drew me in. Bleh.
