Great art as usual! Love the music choice!
The interactivity was a definitely a great addition. The math puzzle took me embarrassingly long to solve (I didn't notice the window above the closet T-T)
The vague delivery was perfect, making the player project their own feelings onto the character thus pulling in player participation.
If I had to suggest something it would be to flesh the world out a little bit. Things seem a bit too vague to keep the player grounded in the scenario. Just small things like maybe you find a book on some history about this world or perhaps an article about how witches in this world are perceived by the common people. Of course I realize that the world is not meant to be the focus here but one can always make the world out to be a reflection of the main character's perception. Small things like that can immerse the player more imo.
The 3D transition was a pleasant surprise.
There were some rendering issues from time to time (just a lil distracting not a big deal)
Overall, a great second VN. Cheers!
