Prop and character size can be adjusted via menu or with an in-game shrink ray, and can be set to change over time (gradually shrink, grow in spurts etc.).
The player can move freely about the environment, controlling the speed of characters, animations, poses, and most notably their scale. Some of these items were originally made for the game, but most have been converted from existing assets. Players can build interactive and dynamic scenes in a range of settings (a blank plane, an island, a house etc.) using imported props, models, and sets provided by the community.
