More about Big Sister

Big Sister is a desktop pet game where players keep a companion that blinks, breathes, and follows their cursor. The character can be dragged, resized (55% to 450%), pinned, locked, or hidden. Players pair her with static or animated wallpapers (GIF/MP4) to create a personalized desktop experience. The game includes natural animations, multi-monitor support, and Steam achievements. No schedules or constant attention are required, making it a low-maintenance companion for daily computing.
