Mutazione is the next project from Johann Sebastian Joust developer Die Gute Fabrik, and is a departure from its motion control title — it's an "illustrated, quiet single-player experience," Fabrik's Douglas Wilson said during the Horizon indie game press conference at E3 2013.
The title stars a female protagonist named Kai who, after a terrible motorcycle accident, wakes up in a strange, derelict town called Mutazione, which is populated by a number of colorful characters. The game is less about a plot for the protagonist to save the world, Wilson explained, and more about a "soap opera" between the player and the town's residents. The game will evolve over time, with its world changing by the time of day and day of the week, somewhat similar to the passage of time in Legend of Zelda: Majora's Mask.
One of the game's core mechanics is a garden which Kai can grow outside her treehouse in Mutazione. Each plant can be collected and tended to, and produces a different sound. Those sounds come together to form an ambient, emergent song, allowing you to "create your own Brian Eno music for airports," Wilson joked.
No release plans are set for the game quite yet, Wilson told Polygon, but Die Gute Fabrik has secured partial funding from the Danish Film Institute.
