+All those half-colored spheres could really need some help. And
+with that, we obviously mean your help, otherwise this would probably
+not be a game, but a movie or something. Grab those fully-colored
+spheres and share the color (and the correct one at that) to bring
+the world order back to normal. Sounds easy? It is. Up until the
+third level or so. Then it gets tricky. But you'll figure it out,
+I'm sure.
