About This Game
Atomcraft is a game where you can pick up and place every pixel of the environment. Pixels react to whatever is around them, and you can build vessels and machines to make reactions happen.
Upgrade your drill and your tools to dig deeper and deeper into the planet in search of better materials!
Smelt ore and perform chemical reactions!
Build machines to do chemistry and extract elements!
and repair your spaceship piece by piece!
Every element on the periodic table will exist somewhere on the planet, although extracting them from their ores may require some creativity!
You can also craft mechanical pixels, such as:
conveyor belts
trapdoors
heating and cooling elements
wiring for signal-based machines
buttons, switches, and sensors
and even logic gates!
Advanced materials like nitroglycerin require careful construction of reaction machines to craft them without the materials exploding!
Delve deeper and deeper through the layers of the planet until you discover every material on the periodic table, repair the systems of your crashed ship, and possibly uncover the fate of this mysterious world!
