This is beautiful! The tone of your story was carried through the gameplay, artwork, and writing. The character designs are wonderful, and I'm very impressed by the aesthetic and visual cohesion.
I'm seconding the other comments about the intuitiveness of the ingredients and which ones correspond to which prompt, but it sounds like you're already thinking about that! My other comment is that the forward and back arrows made things a little difficult to understand how to progress; occasionally I sent a spirit away by accident when trying to go backwards. I would have preferred a "try again" button, and maybe a place to reread their story.
Really good work on this!
