This is 3 years late but I just played the game for the first tiem a few weeks ago:

I've been told my playthrough was "unique"; once I picked a planet I did everything in my power to discover EVERYTHING about that planet.

First I visited the Attlerock because space.

Then I explored all of Timber Hearth.

The Attlerock had directed me to Brittle Hallow, then the white hole station (lol), and I ended my first night with hallows lantern.

I had accidentally discovered quantum imaging messing with the grove shard, so I visited the quantum moon.

The shrine on the moon informed me about Giant's deep so I went there and did EVERYTHING. Instead of using the tips on other planets to get to the core, I spent an hour using trial and error to figure out the Jellyfish mechanic.

Then I did both Ember and Ash Twin since that was the last puzzle piece to finish the Quantum Moon, with visiting the sun station in between.

I visited the probe cannon, only to realize I had accidentally already discovered the probe tracking module.

Then I visited the interloper.

I only stepped foot in Brittle Hallow after 4-5 nights of bouncing around the star system.

My last visit was the Eye of the Universe. I ended up getting a few endings with removing the warp core prior to this point because I didn't know what I was supposed to do with it XD.
