Ooh, I love historical/regency games! I have to admit that I have only just started (still in the carriage) and I find the font very difficult to read. I definitely would recommend font options and/or the ability to increase the font size if you really want to keep the fancy font. I can read it...but it is difficult.
Edit: After playing it through I will say I can't wait to see the rest! I'm impressed that the demo is so lengthy - you really get a sense for the quality of the work. I feel quite badly for my MC - she is having a hard time of it. And all of her options have some issues!
