Well, thanks for the review, TooManyToasters!
After seeing this review, I believe my game had the intended effect on you, at least.
I feel I've really succeeded when I see you mention how well I pulled off the battle gameplay. I'm glad you liked it and I bet many others feel the same way. I put a lot of effort in making it as good, balanced and strategic as possible! I'll try to expand on the game's open-endedness (as in being able to do more) as well.
I didn't focus in storyline very much, but I'm planning to do so in the next release. I'll certainly have to flesh out the story way more in the first chapter, and I've been making it much more influential in the game starting from chapter 2, as well.
Perhaps the originality issue most likely won't be solved easily, as most scripts and game strategies are easily already taken and used by other games... I'll try to event out more.
Thanks again for your review, it's very good feedback!
