The process was highly collaborative, with regular discussions between Flutu Music, BBDO Energy, the NGO Change the Ref, and WebCore. We focused on key decisions like how to use sound effectively to guide players, enhance tension, and avoid overwhelming the player with unnecessary audio cues. One of the key strategies was the careful balance of silence and subtle sounds, using quiet moments to build tension and contrast them with more intense, stressful sounds during key points. We worked with sound textures and unexpected elements to keep players on edge without relying on sudden scares.
