The best this game has to offer is its presentation, right from the start you get that feeling. Big long shots, grainy effect, space probe look, low fidelity audio messages, etc.
Some kind of narrative that gives you an objective that tries to convey melancholy (along with some music themes) which doesn't go anywhere, only gets in the middle of its otherwise documentary/naturalistic vision.
When the propper game starts, you're given control of some kind of ship, a cutting-edge technology that only modifies gravity to move. With that simple but powerful premise you get along, but as the game goes on it fails to expand its concepts, right from the second level you get the feeling that you're just going from point A to point B, not giving any opportunity of expression or challenge.
