I posting here to give you my words of support. I so enjoyed playing the demo (I was quite dissapointed when it ended!) and it's clear that you are creating a VN of superior quality.
In addition to the art, atmosphere, and character development--which were all fantastic--the element I found most engaging was the complexity of the dialogue choices. I liked the sensation of not knowing what the "right" choice would be, and found myself thinking them over intensely, trying to guess the effects different approaches might have. I especially appreciated the emphasis on tone over content, and the 'internal' type choices which determine personality.
What an incredble start, I will be excited to play when the full game is released!
