Great stuff, very meditative :D Amazing art and great music. Love the gravity gimmick once it comes into play, though that takes a bit before you get there (might benefit from accelerating that first phase before you get a star, frontloading more bigger planets at first maybe?). Mouse controls are a bity wonky (also weren't explained well in the text blurb, as far as I can tell you hold mouse on the sides of the container to move, and click either the red arrows or anywhere within the horizontal stripe of the container to drop) more precise mouse control would be great, left/right controls feel a bit slow.
