So far my progress has been adding a dark orb like a black hole, a light orb, and a simple day/night cycle. And also getting stuck trying to get gamepad or keyboard + mouse to work depending on what you have. For some reason, that was way harder than it should have been! Anyways, you can move the player in first person, Left Analog stick for movement, Right Analog stick to rotate the view, or mouse movement to rotate view and WASD to move. Not much gameplay yet, but I hope to start plugging in the fun in the next few hours.
Here's my first build so you can look around.
