I read some of the previous posts, and find the criticisms odd. I read Diego's route first, then Tai's. What impressed me was how much your creativity as a storyteller had improved. Tai's route has much more content cleverly woven through it, with other characters and their sub-stories adding so much interest. I look forward to your future updates not just to see what Happens to Tai, but to Eric and Jay, Dom and Axel, Logan and Tobais, with possibilities of other relations like the dog and kangaroo. You must realize by now you could turn this into a regular novel instead of a VN with descriptive content to replace the visuals.
Far from being upset over Russel's early involvement, I am glad to see you are starting right off with serious character development in this route, instead if it appearing towards the middle.
After reading some of the short sighted comments, I don't wonder you feel a touch of anger and burn out. Please do not let the quality of your work or the progression of your literary talents be stunted by those who think you are writing some sort of short comic book feature.
These critics may be loud, but are hardly in a majority; most people like your work I am sure.
