Great work on the visual design! It's very pretty for a dark-themed game. The ambient sounds to the environment worked really well, too. I liked the writing, and the basic light/dark mechanics, though I would have liked to see the theme play an even larger role.
I didn't find controlling the ship very enjoyable. Though it was a living ship, it still piloted like a stiff boat. Maybe a trade-off of organic maneuverability for man-made parts/additions? I'd also second the feedback of the silhouettes of pickups vs. mines being too similar.
Really beautiful submission! Looking forward to your next game.
