I just finished playing through several endings, and I wanted to write to say, thank you for making this! I liked the style of the character sprites, I really enjoyed the writing and the story, and the voice acting is excellent (I was happily surprised to recognise Artur's VA). I also really appreciated the use of a handbook screen with click-able definitions you find as the visual novel unfolds.
Question: How do we unlock the final handbook definition? I tried to unlock it, but I have no idea how.
