Our take on Your StepSister

The desktop-companion format keeps the interaction focused on one character, so it gives up the broader cast and activity variety found in games built around multiple characters or larger gameplay systems.

What is Your StepSister?

Your StepSister places a stepsister character on the desktop, where she stays over other applications.

The character can be moved, resized, and rotated. Her clothing changes from time to time, while physics can leave her caught in objects such as a washing machine. Players can assist when she becomes stuck. She speaks in different languages and can use additional voice lines from Workshop content. The game also includes achievements connected with spending time with her. Interaction centers on managing the character’s position, size, rotation, appearance changes, physical behavior, speech, and desktop presence.
