I’ve improved the controls in the latest native builds for Windows and Linux. I was a bit hesitant to touch the WebGL version, so the controls there might still feel a bit clunky—sorry about that! Also, make sure to place the 'white hole' (which is essentially a black hole) close to a planet; it will eat the planet like a snack. If you place it too far away, it will just drift in and out, much like humans on Earth
