Havn't played all the way yet, but been looking forward to this since the orginal. Thus far, have quite enjoyed myself.
The graphics are pretty simple, but perfectly suited to a game like this. Enemies remain distinct, and you can tell what things are supposed to be. Gameplay is easy enough, though a simple 'how to' on the main menu wouldn't hurt. I've only started on the plot, but seems to have a lot going for it.
The music and voice effects are good, but get very repetitive very swiftly. I'm not sure how you're doing on file size, but might look into having a couple of options, which randomly select when the effect trigger is set. ie, Aura having three or four things he might say upon ending a battle.
In all, seems a pretty solid RPG I'll be spending some time on this week. We'll see how it holds up over a longer period.
