Limen explores the connection between video games and musical composition, investigating how interactivity can become a creative tool for music through the gamification of sound. The project consists of a video game that is almost entirely sound-based, in which visual elements are reduced to a minimum and the experience is guided by listening and spatial orientation. The gameplay is based on exploration and sound collection, allowing the player to interact with and modify the acoustic environment in real time, which evolves like a dynamic and immersive composition. Limen attempts to describe the phenomenon of creativity and intuition that occurs within a dream. It seeks to answer a question: who is the one who creates and generates the idea? Is it us, or is it an “independent” creator that resides within our unconscious? In Limen, the player embodies this creator and does everything possible to capture and organise the sound of the environment to generate the embryo of a composition.
