Looks like some sort of build your station then take it through procedurally generated universe, ui looks like it needs some work, coming to Steam early next year https://store.steampowered.com/app/968920/Its_Not_A_Moon/

Now their is a version on itch https://hyeson.itch.io/its-not-a-moon which might be a test/demo version.

From Steam
Manage a space station, flying through a procedually generated universe, fight, build and survive in the coldness of space.

Send out your haulers to mine Resources & refine them to craft them into useful modules and ships.

Build modules and ships.
Modules refine your raw resources into materials. Materials are used to build more modules and ships.

Use defensive modules and ships to destroy the enemy.
Ships come in different sizes with different stats. Do you need a cheap fast fighter? Do you prefer to wait for the materials to build a slow but sturdy gunship?
It's your choice!

Manage your energy and fuel. Should you run out of energy, your productions will stop. Turn off not needed modules or build power plants to generate more.
Should you run out of fuel, your life support fails.

Travel through a vast universe to find resources, unique places and enemies.
Decide where to go. The next galaxy might be more dangerous but it might also have the resources you need.

Research new technologies to unlock new vessels and modules or improve the ones you currently have.

Build modules that help you survive
Produce different ships that fight, haul or trade for you
Manage the energy consumption of your modules
Explore the vast universe
Research new modules and ships..
..to Crush your enemies
see them driven before you
and scavenge the debris of their space ships!
