Like others have said, the art in this game is excellent. The style is cohesive and it all really works together to build a whimsical autumn mood.
Regarding the writing, I feel like you were able to capture what you trying to go for. Magical, cozy, autumn, mostly cheery and maybe a little solemn at times. The only suggestion I have is to make the overall conflict of the story more clear. I could tell that I was going from one task to the next (and the writing and art made it enjoyable), but I couldn't tell at any point where I was trying to get to. Maybe somehow tying in the "last day together" part at the beginning and then during the day you can enjoy the little moments at the market and the cafe that much more. I appreciate the depth you went into character building on the witch. I would have preferred for it to be a "he/his" or "she/her" pronoun instead of "they/their", only because I couldn't tell at first if the story was 1st person or 3rd person.
Really liked the ability to do Auto play. I'm unfamiliar with this genre, so maybe that's a standard feature? Anyways I found it helpful.
Looks like you added lots of settings too. I didn't try out all the configurations, but the interface was clean and appealing. Great work on the UI!
All in all, great work on this!!
