I remember the first time my ship was destroyed as my crew slowly faded away. When it blew itself to bits, I had initially thought I must have hit one of those famous invisible planets!
Makes me wonder though, why does your ship blow up when the crew dies?
It wold be better instead to hear the crew choking to death, and as the Last man dies, the ship begins tumbling and drifts away from the camera into the void, as the screen fades to black...
But I guess that's too subtle. Blammo! Everyone knows what an explosion means!
I suppose the Last guy leans on the ol' Self-Destruct Button (tm) rather than allow the pirates to scavenge the ship.
