Gameplay
Higurashi is a murder mystery game described as a "sound novel" by 07th Expansion. A sound novel is similar to a visual novel in that the gameplay requires relatively little player interaction as most of the game is composed of text dialogues. The original release contained no voice acting for the characters. While a visual novel's basis would be the visual aspect, as the name suggests, a sound novel's basis takes more care in producing an atmosphere via the music, sound effects, and the story itself.
