hm...
well, I'm playing it as we speak, haven't gotten super far yet, but there are a few things worth note right off...
1. I like the idea of the little video intro before the main menu (The one with Start, Load, Quit) but I think there should be a way to skip it if you've seen it before. Also, the prompt that asks you if you want to make it fullscreen should come before this intro, not after... it just didn't feel right, although that's just me.
2. I think there should be a little more introduction to the story at the very beginning. Reena starts the game by saying 'oh, I must have been dreaming.' That dream could have been a better intro to the story, even though there was that little video I mentioned earlier.
3. I personally didn't find the combat too hard, although I did have Kira in the party before I fought
I'm liking the look and feel of things right now... its really good. I'll finish the demo, and give you some more feedback, but right now, I'm simply going to say keep up the good work!
