Very simple game, all about the ambiance wich I love. However I think even for such a small game that there is room for improvement. For instance I feel like sound wise and control wise there's nothing to add, it's prefect, but I feel the graphics could have been much more detailed. The ground texture is a bit repetitive, the spaceship part look too much like placeholders and so does the ship. Also there is no skybox and you can cleary see the limites of the moon. Some high moons or big crevace would have been really nice with a lot of distance to feel like you are indeed in a planet and not a game.
If all those little details would be filled, for what it did, to me, the game would have been simply perfect !
