Serena Nelson writes: "In Essence you play as a person with no memories. You don't know who you are, where you are, or how you got there. Similarly, each world that you come across in the game are also missing their memories. In fact, the first time you land on one of twenty planned worlds it's all black and white where you can't really interact with anything. As you progress through the story you'll pick up fragments of memory, adding color to the world and unlocking the mysteries of the place."
