Love the demo so far, and I was hooked at the end. I was so ready to cause trouble until boom, end demo.
A few things with the background as Moira's color schemes are grounded red, it was hard to focus on Moira as some of the backgrounds (japanese shrine and living room especially) have shades of red. It was hard to focus on Moira because of these "out there" background colors. It would help to slightly blur the backgrounds or make them neutral to allow Moira to pop out more.
Overall, great job with the visual novel!
