THE MUSIC IS THE LEVEL SUBSØNIC is an audio-reactive twin-stick bullet-hell where every wave, every pattern, and every boss is built from the song you're playing. Enemies spawn on the onsets. Bullets quantize to the beat. Boss phases follow the track's own structure; the verse builds, the chorus swarms, the drop is a wall. Beat the song and you beat the level. TWO WAYS TO PLAY Curated packs — hand-tuned experiences shipped with the game, analyzed and balanced track by track. Press play. Bring your own music — import your own mp3, flac, wav, or ogg. SUBSØNIC analyzes it offline in seconds, detects its key and structure, and turns it into a playable bullet-hell stage. Your library becomes the game. SHOOT IN KEY SUBSØNIC reads the harmonic key of whatever is playing and tunes your fire to match. The whole screen blooms in time; austere vector geometry, heavy bloom, reactive to the mix. It is loud, clean, and built to be watched as much as played. EARN THE GRADE Every run is scored. Chase the S-rank, clear a stage without taking a hit, and push three packs of escalating intensity toward their finales: three distinct megabosses, each one a fight tuned to the song behind it.
