Hi there! ^_^ I enjoyed my time with this game! Your art is so gorgeous - I especially loved the demon's design (so beautiful) and the CG that you get from ending 5. I definitely paused my reading for a moment just to admire those! The BG art stood out to me as well, I thought that the single-color palette for each one was really unique, and the colors you chose suited each background ^_^
The story was very gripping. In very few words, you showed clearly Amelia's history with the Baron and the abusive situation of the present. I was rooting for her very early on. I also really, really liked what you did with the Baroness a lot - for a character who is only physically present for one scene, she's fairly complex and has a lot of weight in the story both before and after we see her on-screen ^_^
ALSO you would not BELIEVE how sad I was when I got ending 3 haha;;; I didn't realize that combination of choices would lead to that outcome and I was SO sad I felt like I'd betrayed Kuro >_< so props to you for making me feel emotionally attached to such a short experience! Thank you for sharing your game with us!
(Also, this project is set in an existing universe? :o you should drop some more info in a reply to this comment and/or link it on the itch page! This is the first of your work that I've seen and I'd love to see more.)
