The game took 18 months to develop, and the team drew inspirations from homemade toys, such as miniature cardboard towns, when they were creating the game. The main theme is friendship, as the player needs to become a 'supporting friend' for Louis as they helped him solve various problems and puzzles in the game.

The studio worked with Swedish writer Sara Bergmark Elfgren to create the story. For instance, players can use the PlayStation Move controller to rotate houses and discover what can be found inside. Players can also explore the world of Sancourt and interact with various non-playable characters living in the city. The Giant is tasked to assist a young boy named Louis by manipulating the game's world, lifting items and solving puzzles. In the game, the player assumes control of the titular Ghost Giant.

It was released for PlayStation VR in April 2019 and Oculus Quest in February 2020. Ghost Giant is a virtual reality puzzle game developed and published by Zoink for PlayStation VR and Oculus Quest.
