It took me a fair number of attempts to finally get through and memorize the layout, I'm glad the ship was not much bigger than it was otherwise my pea sized memory would not be able to deal with it.
But wow this had really great pacing in the layering and buildup of the music. The ending was very fantastic and chilling!
The final winning run was like a well scored movie scene, with rising tension right up to the end. The transitions between parts were very smooth! Great work!
