It's Full of Stars is a journey of self-exploration through the guise of making constellations in the sky. The player is provided an assortment of stars, each with their own label. The player connects stars together to make a pattern in 3D space. As the player goes on, the stars slowly disappear and get further from the center.
If the player reaches out for distant stars, it might happen that others notice and try to fit the player into a box by making a new connection that cannot be changed. The player can choose to stick to small connections, but then the constellation may not reflect well.
