I love the card portraits and the old paper dialogue interface! The art style isn't just good, but it's also very consistent and applied to all of the game's visual elements! The detailed backgrounds look great and the game gives them plenty of space to shine. Music and sound effects are very fitting for the atmosphere. I enjoyed the narrative style. The puzzle design was really neat, but I couldn't really figure out how to get started without the solution video. The hint section is a good way to help with that, maybe it could go a bit further.
This visual novel has an unmistakably distinct artistic identity. What a fantastically good presentation!
