Didi, an inquisitive 9-year-old living with her mother in a 1920s noir world, manufactures a landscape of shadows populated by her lone, best friend, Dawn. Dawn is a young woman, more mature and powerful than Didi, and has the ability to shift between the real and shadow worlds. In Didi's reality, Dawn can climb shadows as if they were solid ground, allowing her to scale areas unreachable by flesh characters. She interacts with few real-world objects, and people, aside from Didi, are invisible to her -- only their silhouettes exist.
Contrast is a puzzle platformer, starring Dawn as she shifts between shade and density, helping Didi as she follows her mother through the dark city streets. The game is infused with jazz and tainted innocence: Didi's mom, the cabaret singer; her dad, absent; and a decrepit circus, just rolling into town.
