This game's got a really neat vibe to it. It reminds me of Highfleet in some ways with the UI, but unfortunately also in obtuseness. I get that some of the puzzle is figuring out how the UI works, but a small in-game explainer of the objective would do wonders to get people over that first bump. I like how you used the thruster(?) mechanic in two quite different ways.
I think this game could do well with quite a few more mechanics added on, and they should probably interact with each other more. Layering your mechanics is a good way to add depth to puzzle games.
