A really nice game with good visual, art style and sound design, the movement of the spacecraft feels smooth and the control feels responsive, and I love space games:)
I do feel thrust above the second level is a bit redundant in the current gameplay loop, it's difficult for your magnet to grab the junk during those speed, and the map size and density of junk field doesn't justify using them for travel either. They also consume fuel faster, so overall just use the first level ends up being the most efficient. Maybe some added features such as environmental hazards would give more reasons to use them.
