“After a helpful (though light) tutorial, Universe Sandbox offers little guidance for aspiring unmoved movers. A more robust set of tutorials, a manual, or even the use of Steam Achievements to encourage varied behavior would go a long way toward helping players make their own music of the spheres.”
