Atomcraft

If you’re on the fence about Atomcraft, just get it. This is an absolute gem of a game. At first glance, it looks like a retro pixel-art sandbox, but under the hood, it’s one of the most clever crafting and engineering games out there. Every single pixel on your screen has real physics and chemical properties. You wake up stranded on an alien world, and the ultimate goal is to repair your crashed spaceship piece by piece to get off the planet. The main hook here is actual chemistry and automation. There are no magic “one-click craft” blocks. If you want to smelt ore, synthesize chlorine gas, or refine nitroglycerin, you have to build the actual machinery to do it. You harvest raw materials, manipulate liquids and gasses, and set up your own reaction chambers using conveyor belts, heating/cooling elements, pumps, and even logic gates. What makes it click: * **True Sandbox Freedom:** You explore the depths of the planet, dig for elements across the periodic table, and solve engineering puzzles completely at your own pace. * **Rewarding Problem-Solving:** The game gives you the recipes and reactions, but figuring out how to mechanically contain the heat, pressure, and volatile gasses without blowing your base up is entirely on you. * **Real Science Logic:** A lot of the reaction chains behave just like real-world chemistry, making it ridiculously satisfying when a complex automated build finally works. It scratches the exact same itch as games like Noita, Terraria, and Factorio, but with its own unique chemistry-sim spin. It is easily worth every penny, and I really hope the developer keeps building on this foundation for a long time. Highly recommended!

it is a awsome game for the one how love chemestri

most realistic gamified chemistry simulator to date. Very fun too.

hell yea, chemistry lab factory must grow

The pixel sandbox of Noita meets the chemistry of Oxygen Not Included, this game rapidly shot up to one to one of my favourite sims even just playing the demo. Don't let the simple graphics fool you, they're not talking it up, you'll spend countless hours learning the chemistry and physics challenges of acquiring every element on the periodic table, and it's an absolute blast trying to recall the long forgotten details of your chemistry classes. Runs like an absolute treat too.

oh my science 10/10

* 125 hours in 18 days and I'm fully employed. Send help. * It has almost Dwarf Fortress levels of chemical and thermal simulation, automation with conveyors and logic gates, pixel physics, and a very active dev. Every time I think I'm almost done he puts out a big content update. It's super niche, like an extra nerdy 2D version of factorio, but the dev and small group of players seems to love the project. I sure am having tons of fun with it.
