Those screenshots look awesome in graphics, I'd adore a youtube-video about possible levels, while that sand-surface maybe could look quite more "less smooth/like no wind carried away some steps there"?
I like the shadowing of the rocket and sun's reflection, same as the sky's colours. Are the day/nighttime-differences like an added mood, stars, fog?
Its landscape looks cool in 3D, also the floor "tiles" there & maybe the 'smoking' part of the screenshot could be more like grey/black/silver, than solid black in colours?
