I agree with Kaz! They mentioned the plot, the agency, and the writing; it all sort of flows very nicely into a coalescent sort of intrigue, giving the player a nice level of agency while permitting each character to have a fantastic personality on their own time and as to not distract from the story's direction too much.
VFX-wise, it's very pretty! I adore the scrolling-thing you did; it looks far better than the plain old Harlowe 3.1 white-on-black abomination that I was stuck with.
The story itself is engaging, delivered in little tidbits that aren't too long yet aren't too short, either. It's pretty nice, easily-digestible, and rather comfy as well, aside from the demonic-deal overtones.
Very nice, very good! But What does Regular Girl want most? The world may never know.
