I really liked the visuals and the artstyle, I love seeing pixel art that doesn't reduce itself to chibi or chibi-like sprites and the portraits in the text boxes really helped add more detail to the characters.
The story was quite captivating with the way it set up the idea that she was being kept in captivity and isolated from everything and everyone outside her dreams, however I think a way to bring the player more into the game would be to have maybe a level based on her dream that works like a tutorial, so the player can start interacting with the game and get more invested.
The gameplay could use some work, specially when attacking, the spiders sometimes felt that they were too short and the attack would not hit them. In a few areas, the spiders had colors that were too close to some backgrounds and sometimes I would not be able to keep track of their positioning when they jumped.
Also when collecting the berries right after getting the sword, I had no idea if you had to hit the bushes to get them I was just playing around and ended up having all berries with me, maybe have the bushes with a highlighted outline or a berry icon pop up when collecting them to just clarify that!
All in all, the story and art are pretty good as they are, you should turn some focus now on developing more gameplay mechanics and brainstorming better level designs (make sketches of them, if you don't like them then you can throw it away until you make something that you like better!)
