About this game
Description
Supplied by the Steam store
Stella Astrum is a whimsical factory game where you manage elemental resources to form Stars, Planets, and more. Use your skills to unlock upgradable factories, nurture colorful celestial bodies, and shape an expansive galaxy. Sit back, relax, and amplify the universe beyond its artistic limits!
As a Galaxy Operations Director in training, you must learn how to harness the elements to build your own Galaxy in this ever-expanding universe. Using the Black Hole at the center of your galaxy, you will store elements to engineer factories to fuse Stars, Asteroids, and Planets.
With the help of Nebulas, factories will pull resources like Hydrogen, Helium, Carbon, and more to cater to the style of your system. Now you can see what it’s like to have a personal galaxy filled with purple, blue, orange, or rainbow celestial bodies!
From Protostars to Supergiants, these stars are not just for show. If you can keep them alive, your stars will produce more elements you need to form a more beautiful, ever-expanding system.
In Stella Astrum, you are the creative director. The emptiness of space is your canvas, the elements are your brushes, and the stars are your medium. The universe is at your disposal, so push the boundaries of the game’s limits and share what you create with friends or on social media!
