This was a fun visual novel! I think you made a good choice for the introduction music cause I was jamming along instantly. I liked the magical girl designs (especially Seassa, I'm a sucker for the elegant type and swords), although I felt the monster designs were lacking a bit comparatively.
Really liked the effects that you used in this, especially during the Sadistic Ending. It felt very in theme with the "falling into despair" that had been happening throughout the route. Adding the bounciness to the sprites also did a lot of good to add a bit of life to each of the characters.
Also, wasn't seeing panacea candy coming up! I thought she was gonna learn how to shoot huge cascades of candies or something, so I got a nice surprise too!
