Nocturne Hills
Build and Play Music for Peace
By night, sad and angry spirits come — restless spirits. Spirits that tear down walls and settle over the people they touch like dark clouds, restless spirits!
Your mission is to gear up with your instruments and play. With your music, knock on the door of beauty. Play with your people until the sun rises.
Spirits who find peace relax, dance, and grow wings to rise into the sky. Some leave gifts behind as they ascend.

Core Concept
Creative Building. Character Creation. Musical Defense
The game is a sandbox experience where the player combines creative building and design with music.
Players construct structures, design characters, and create their own music by assembling pentatonic-based music modules. Thanks to the pentatonic system, different melodies harmonize naturally when played together, allowing players to create layered and aesthetically coherent compositions without requiring formal musical knowledge.
Building, character design and music creation mechanics are integrated into a single creative and strategic gameplay loop.
Unlike traditional sandbox, defense is not based on weapons or combat units. Instead, strategic placement of musicians and harmonic aura ranges replaces conventional warfare, turning city layout and musical composition into a unified defensive system.
