Just got done playing through this, and was a little disappointed by the lack of choices up til the end of the demo. Even just a few "cosmetic" choices placed here and there can help make it feel like the player is playing rather than just reading a story. That said, I /did/ enjoy the demo and what little we got to see of the story! The character interactions were very entertaining and the group plays off of each other very well.
Out of the LIs I think Thrace and Kadan wound up being my favorites. I'm also interested in learning more about Roxas. Aiden... I wanted to punch in the face. This isn't to say that he's a bad character. He's just not the type of person I personally would ever get along with. Iandir... was bizarre. Although I think that might have more to do with how blase he was about being /owned/ and used for transportation. Cultural shock on my part, lol!
I see you were asking after the voice acting below in another comment, so I'll put my thoughts down on that too. The voice acting threw me for a loop in the beginning. I didn't realize it was voice acted until the Dad's lines started playing. His acting was pretty good. Aiden, Thrace, and Roxas all have voices that fit their character sprites, and were pretty good as well. Kadan's voice was not what I was expecting at all, but after the intial surprise it seemed to fit by the end. I think that was more influenced by the type of voice that usually gets assigned to characters with similar designs from other games I've played. So I will say he passes with the others. Maybe a bit more inflection in his voice? As I said, I did wind up liking it by the end of the demo. Iandir's seems to lack... something. I'm not sure what. I feel like maybe in trying to make him sound like a very calm and friendly sort, too much emotion is being left out??? I definitely think there needs to be more inflection.
My only other critique, I think, is sometimes the voices seemed to play at different volumes. There were also a few times the voices got low on purpose, as part of the acting, but it made it harder to hear them. I had the music volume pretty low and everything else left at 100%. I was also not wearing headphones, so it might not be as noticeable if I had been. Still something to look at, I feel.
So my final thoughts: looking forward to seeing this funded and finished! I will try to chip in what I can when the campaign goes up as I enjoyed the demo quite a bit. I hope I didn't come off as harsh, because all I want to do is offer helpful criticism. Good luck and keep up the good work!
