Mom Stolen in Space follows Sora after a space shuttle trip goes disastrously wrong near a small black hole. He wakes in an abandoned colony, separated from his mother, Mitsuki, and his friend Tarou. The story centers on finding them, piecing together what happened, and locating a way out, with the colony’s empty corridors setting an unsettling backdrop for the search.
Progress comes through exploration and investigation rather than combat described in the available details. Sora searches for clues in objects left behind by former residents, observes the surroundings, repairs broken machines, and solves simple puzzles to reach sealed or hazardous areas. The layout spans multiple floors, ducts, and collapsed sections; clues and items can open new locations, while revisiting earlier places can reveal additional story scenes. The game also describes occasional regroupings with Mitsuki and Tarou to plan how to survive and escape.
The premise gives the exploration a personal objective, while hints for puzzles are provided during play. The description also mentions a special story that becomes accessible from the main menu upon completing the game, adding a further narrative element to its documented design.
