01 / THE GUIDE
Visual‑novel storytelling
The narrative is delivered through visual‑novel‑styled scenes, allowing players to switch between the five interconnected high‑school girls. Each perspective reveals a piece of the larger mystery, and the story progresses as players advance through musical encounters.
Full Japanese voice acting and illustrated artwork accompany each dialogue segment, reinforcing a world where emotions are displayed openly and lies are forbidden. The narrative moments are directly tied to the songs, making the music reflect the characters’ experiences.
- Observe dialogue cues; they often foreshadow the style of the upcoming song.
- Listen for changes in the soundtrack that signal a shift in the story.

Rhythm and control system
In Falsus uses a mouse and keyboard control scheme for its rhythm gameplay. Notes travel across a sweeping aerial field, and players must hit them in time with the music.
Four difficulty levels increase both note density and field complexity, providing a clear progression from basic flow to higher mastery as players become more comfortable with the system.
- Begin on the lowest difficulty to learn note patterns before moving upward.
- Adjust the difficulty setting to match your current skill level.

Song catalogue
The game features over 70 tracks, more than 40 of which are original compositions from Japan’s independent music scene and international artists. Songs span many genres, giving each encounter a distinct musical flavor.
Each track is paired with a specific narrative moment, so the music directly mirrors the events the protagonists experience, reinforcing the link between gameplay and story.
- Explore the track list early to become familiar with genre variety.
- Use the custom volume controls to balance music and sound effects.

Cards and blueprints
By completing challenges, players collect materials that can be placed into blueprints. Each blueprint acts as a puzzle grid, and the arrangement of materials determines the stat boosts and bonuses of the resulting card.
Cards display artwork from narrative moments and can be equipped up to five at a time, allowing players to customize their approach for each song based on the bonuses they need.
- Experiment with different material layouts to discover new bonus combinations.
- Keep a varied set of five cards ready to adapt to different song demands.
