Big Sister

A gentle companion on your desktop This is a desktop pet game. When launched, she settles into a corner of your desktop and quietly stays by your side while you work, study, browse the web, or relax. There are no schedules to complete and nothing that interrupts what you are doing. Place her wherever you like, watch her blink and breathe, and see her turn her gaze toward your cursor, adding a little warmth and life to everyday computer time. A lively, naturally animated character - Real-time gaze: Her head and eyes smoothly follow the direction of your cursor. - Blinking and breathing: Natural idle movement keeps the character from feeling like a static illustration. - Physics-driven movement: Hair and clothing sway gently with her motion. - Detailed at every size: Character rendering is optimized to remain sharp and detailed when enlarged or reduced. Place her exactly where you want Hold the character to drag her anywhere on the desktop. Hover over her and use the mouse wheel to resize her from 55% to 450%. Position and scale are saved automatically, and placement can be restored across multi-monitor setups. Switch between always-on-top and normal window behavior at any time. Keep her in front of your windows, or let her stay behind them when you need to focus. Quiet companionship without getting in the way Transparent areas around and inside the character support per-pixel mouse passthrough. Empty spaces between the legs or around strands of hair will not block normal desktop interaction. When you want every mouse action to pass through the character, enable Lock mode. You can unlock her again from the taskbar icon or system tray menu. Convenient desktop controls - Drag the character with the left mouse button and resize her with the mouse wheel - Right-click the character to open the quick menu - Use the system tray menu to change settings, switch characters, lock, or exit - Choose whether the taskbar icon is visible - Switch always-on-top behavior at any time - Start automatically with Windows - Automatically save language, position, size, character, and desktop display settings - Single-instance operation prevents duplicate desktop characters from launching Expand your collection through Steam Workshop The game includes one built-in desktop pet character and supports additional compatible characters from Steam Workshop. - Browse and search community characters - Subscribe, unsubscribe, and switch directly to downloaded characters - Upload your own compatible desktop character and preview image - Update or delete Workshop characters you published - Validate model structure, file paths, and resource size before publishing After you subscribe to a compatible Workshop character, Steam downloads it and the character appears in the in-game character selection menu. Interface localization for more players The game includes interface localization for 30 languages. On first launch, it reads the Steam game language and, when no separate language is selected, uses the Steam interface language as a fallback. You can change the language later, and your choice is saved. Small goals alongside the companionship The game includes 10 Steam achievements, adding a few small mementos to the time your character spends on the desktop. Whether you are focusing on work, studying quietly, or taking a short break at the end of the day, she stays on your desktop without getting in the way.
