 The game was developed to be able to be controlled by the player with only the mouse, after it was suggested by Yu's father.The developers felt that this control scheme forced them to make the gameplay fluid and easy to grasp, though they also added the option to control the game with a keyboard or Xbox 360 controller.Yu and Holowka considered the "hallmark" of exploratory games to be a sense of loneliness, which they made a part of the narrative, but also wanted the player to get a sense of Naija's character.
