From the developer:
Space 2048 moves the old 2048 game into outer space with great visuals, animations and the entire universe as background. Move entire planets to get to your score, surrounded by galaxies, suns, and asteroids. You need to use the arrow buttons to move to the left, the right, the top, or the bottom. All planets will then move into that direction as far as they can.
