I won't lie, I havn't been enchanted by a demo for quite some time like I was with yours. I love the fact that you get to choose 'unnatural' hair and eye colors. I love the fact that I can choose to have my MC speak or not.
The story of King Arthur was one of my favorites growing up so now playing a version of it makes me incredibly happy. Your writing style is easy to read and I think it's why its also so eady to get into the story.
And as noted by RainyNight, seeing the MC through others eyes makes the story greater.
I can't await seeing what will happen next in the story as well as looking forwards to the next update.
PS: Do I get to choose the MC's age at some point? Or is it set and I just overlooked it?
