My prediction,( the game comes out in two years :s, this will be forgotten ). ( assuming a cube ) The gravity works orthogonal to the side you are on( 6 sides ), no matter your position. There are 4 imaginary planes for every side. You need 3 point to get a plane in 3d space. Those points for the 4 planes are made from the center of the cube and 2 points of the side you are on( the planes are rotated 45 degrees relative to the sides ). So for one plane that would be center of the cube and top-left and top-right sides. For another that would be center and top-left and bottom-left, and so on. If you cross one plane the gravity changes 90 degrees, depending which one you crossed. There are interesting thing about this model. For instance; for larger distances, you don't fall in a straight line towards the planet, but in a sine wave like curve. Orbits will remain circular with inclination changes, so the square orbits in the video are not physically correct. --- Also, you will not be able to reach the center of the planet. At most you will be able to reach about 80% of depth, where the cube sides are still large enough to not constantly switch directions.
