I really liked the parallax effect with the stars;
The game, however, felt slow to progress. At the beginning, the effects of the upgrades were hardly noticeable, and unless you are moving super fast like that one commenter, you're not going to accidentally walk into one of those tiny asteroids.
Most of the game was spent flying around looking for asteroids, because they spawn so far apart. There also wasn't any real threat because they are so small.
