The music doesn't play behind the battle. It runs it.

Signal Break is a horizontal bullet hell roguelite where the soundtrack controls everything. Real audio analysis choreographs the entire battlefield: bass frequencies spawn heavy enemies, treble sends fast harassers darting across the screen, every enemy steps on the beat, and the tunnel itself breathes with the track's energy — loud sections squeeze the walls in, quiet passages open up breathing room. Bosses aren't scripted; their attacks ride the music's own LFO and filter wobble, so every drop is a composed encounter.
Between levels, a roguelite engine keeps runs fresh: pickups from common to legendary, a shop to build your loadout, and five weapons with sixteen modifiers — many of them music-hooked, like crits that only land on the downbeat.
Every song is a different fight. Play the hand-authored official soundtrack, or import any MP3: the BattleMap Editor — a DAW-style authoring tool that ships with the game — analyzes your music and lets you compose enemy choreography, terrain, and boss fights against your own library, then share them on Steam Workshop.
Every official track is original music, cleared for streaming and video. Play it, record it, monetize it — no mutes, no copyright strikes.
Bring-your-own-track levels play music from the player's machine. Streaming copyrighted songs is on the track, not the game — use original or royalty-free music to stay clear.

SpiFFWorKs is a solo independent studio in Fresno, California, founded by Doug (DiGGySpiFF) — developer, designer, and Ableton-wielding composer. Signal Break is the studio's first title: a bullet hell that takes music seriously as a game mechanic, not a vibe. It's being built in the open, tools and all.
