I'll start by saying I thought your game was fantastic. It fits the theme well, it's a super creative concept, and it's fun to play.
I did run into two odd bugs. After dying on my first attempt, I noticed that enemy ships stopped spawning during the next playthrough, which made it really easy to get to the end. Second, I noticed that sometimes it's actually possible for the player ship to shoot itself. I usually managed this when I had the ship in a spin, but it wasn't consistent.
One additional bit of feedback I'll give - the opening informational text scrawl felt like it took a bit too long to get through. I think an easy fix for that might be to let the player click or hit some key on their keyboard to skip the actually scrolling of the text and just read the finished paragraphs (like a lot of RPGs let you do). That way people can read at whatever pace they prefer, rather than the pace the letters appear.
Great job overall. Thanks for making this and sharing it with us!
