Flux Empyrean

Here is an excerpt from Flux Empyrean's description on Steam:

You’ve been absent. Perhaps you once called this world home, but it moved on without you. Where were you? How long has it been? Alone on a boat in a sea of Flux, you set off without destination to find answers.

The entire planet lies before you. No matter where you go, you find a unique trace of the past. Lost journal letters. Remains of a great temple. Derelict research papers. Ancient conversations between peers. Soon you start making connections, and previous discoveries grow in weight.

Knowledge is progress. There is no combat, waypoints, or skill trees - just you, your ship, your tools, and the waiting world.

Constellations rotate overhead as you glide over the waves. You learn to sail by the stars, using the sky as your guide.

Each location you explore offers up new mysteries and answers. You take note of your discoveries in your journal for later.

You pause after reviewing your notes. The strange puzzle from a previous location begins to make sense. You know what to do now.
