Hey, I've tried it, and here's my real feedback.
The game is great, except if somebody wouldn't read the first post about Zusae's wife dying, they wouldn't understand the introduction at all. The maps... Slinturi ticks me off. It looks very... well, you know. Rectangle shape houses that have difference only by the roof's color, huge houses lining the edges of the map except the pathways to other maps... it looks like Slinturi is separated into several small districts. But everything else is fine. Possibly lessening the count of armor in the castle would help.
The battles, well, that's one system I've seen elsewhere, where you can use certain techniques only when you get attacked a certain number of times. I love it.
The only complaint on battles is that either make them easier, add other types of potions(you know, High/Full/whatever) or make the healing item cost lower. I died while fighting Forcia, and I had little potions to heal myself.
By the way, how do you jump? I didn't manage to find anything in the tutorial about it.
Anyway, this game is amazing. All I can say. Fix some things, and you'll get a really,
REALLY great game.
