I can definitely see the design coming together! Very interesting elements and a good emphasis of cold-hearted emotions and frozen feelings!
The one thing that I would provide some suggestion on is breaking up the long dialogue segments into more gameplay activities. It's fine to have it be almost purely dialogue if you're going for the visual novel, but for me I found myself occasionally skipping some dialogue because I was starting to get impatient. I've got ADHD and I'm not that much of a reader, so this kind of game just isn't my cup of tea, but I can still tell you put a lot of hard work into it, and if it's heading in a direction you like, than I encourage you to pursue it!
