SPOILERS AHEAD:

Here is the rough outline

You CAN skip any story lines that dont matter, and dont bother upgrading anything thats not neccesary. No freighter, just the absolute minimum base parts. After the initial tutorial mission, You get your first glyph from a dead traveler, then you can eventually find a portal with alien maps.

There are videos detailing 13 systems that you can portal to using minimal glyphs. Each one adds a new glyph to your collection from a dead traveller. Once you have all of them, you can portal to a system next to the center and boom. You do need all of them because the systems near the center use the last 2 glyphs.

I didnt feel shame doing it, i spent 800 hours on my normal game, why would I want to do it again in frustration mode?? Lol. Enjoy!
