The player controls two objects: the protagonist, a little shadow puppet girl named Greta, and a physical ball of light. Using the ball of light, the player can manipulate shadows which become solid and allow Greta to walk on. The length and angle of the shadows depends on the positioning of the ball of light. The game doesn't use any dialogue to explain the story, instead using characters' actions and visual cues.[4] The player explores four different time periods, Indonesia, China, Turkey, Greece, and 19th century England, each with its own unique style.[5] Every character is a shadow puppet, as is the rest of the environment. The characters and foreground are black while the background is in sepia, replicating the style of tradition shadow play canvas.[6]

Head developer Michael Chu explained his inspiration was from playing with shadows on the wall as a child, and realized there were a lot of ways shadows could be used in game development.[7] After deciding on the shadow puppet style, they researched it by visiting puppeteer Richard Bradshaw, who gave them a tour of his workshop and gave them a demonstration of creating a shadow puppet as a reference for artist Yosha Noesjirwan.[8] Noesjirwan also gained insight for the Indonesian shadow puppets through his parents.[9]
