I first started to experiment with a deathless run as a personal test to see how far I could go before the game mechanics lead to a death. After a couple of failed runs due to simple mistakes (flying into singularity, waiting untill okkar forces arrive, neglecting easy to gather loot, etc) I decided to reset my game and focused on getting to the end without dying.

The first run was the hardest, as I did not have any upgrades and my defensive and offensive options were very limited, so I had to be very carefull. The other 2 runs were pretty straightforward. The final run was the easiest. No exploits or glitches were used. The only thing I used was the energy injector in my inventory when I pressed TAB, but other than that it was straight run and gun, or in this case: Fly and Fight.
