Darn, I tested the sound effects at 0% but not the music, because not being able to disable sound effects in a game is a deal breaker for me. Space Sweepers is my favorite movie I've seen this year (though without spoilers I'll say I think it would have been more powerful if it had ended just a little bit sooner) and was a big inspiration in the theming of the game after seeing the mechanical theme. If I trusted my ability to make the cord on a javelin look good in the time constraint it would've been that instead of a tractor beam. That particular action scene near the end of the movie was the visual I was going for with how you kill ships within the game. 

As for how I feel it fits the theme, a grappling hook was the first thought that came to my mind after watching the theme announcement and I wanted to put a twist on it by putting it into an environment where it could really act on inertia and shine. Every object has a mass set as a percentage of your ship's mass and the tractor beam maintains total momentum between you and the item you are grappled on. When grappling a large asteroid which has 500% your mass you will accelerate towards it 5x faster than it accelerates towards you, for example. The "chain"  concept is most clearly visible if you fling a small asteroid and then hold a beam on it as it flies past you; if you maintain the beam you and the asteroid will fly through space in an orbit together around a point between you as their mass is identical to yours. Which, incidentally, is a pretty decent strategy as the number of aliens increases though you may need to use the maneuvering thrusters a bit to avoid crashing especially if blaster bolts hit the asteroid and alter its trajectory.

I'm really glad you liked it and happy to see another Space Sweepers fan. After the judging period is over I'll be updating the game with a few fixes including the music one you found, thank you!
