Info about Atomcraft:

Official game description:
**_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!

Common complaints:
- Lack of automation and QoL (weight 0.35): Players highlight the inability to automate mass production, manual mixing for carbon powder, and repetitive ore refining. A magical inventory further removes any incentive for automation, and basic QoL features like slider bars for item transfer are missing.
- Chemistry and physics inaccuracies (weight 0.31): Players note significant inconsistencies between real-world chemistry and the game's mechanics, such as CO2 being heavier than gasoline vapor, lack of heat conduction, and gases not floating through liquids. These break immersion for a simulation game.
- Performance issues and stuttering (weight 0.28): Multiple players report significant stuttering, especially later in the game, even on non-potato PCs. Snowfall, rain, and general gameplay cause frame rate dips, affecting the overall experience.
- Insufficient tutorial and guidance (weight 0.23): The tutorial is too short and does not adequately explain devices or mechanisms. Players report confusion about how to get steel and frustration with missing recipe information, such as for oil reactions.
- Poor exploration and building (weight 0.22): Both exploration and building aspects are underdeveloped. The 2D environment limits machine building, and there is no vertical transport except freefall and gas buoyancy, reducing creative freedom.
- Pricing and value concerns (weight 0.22): Several players feel the asking price is too steep for the current content, which is not substantially different from the demo. This leads to labeling the purchase a waste of money.
- Visual and UI issues (weight 0.22): Pixel art hurts players' eyes, help text overflows windows, and the language settings location is not obvious. These UX problems make the game less comfortable to play.
- Lack of content and comparisons (weight 0.21): Compared to games like The Powder Toy, this title lacks exploration and content. Players fear it might become abandonware, as no major improvements are expected.
- Forge design too restrictive (weight 0.19): The game's reaction range is too small, forcing forges to be compact to save fuel, which leads to material funneling issues like over-packing and insufficient material. Turbines and heating elements also don't work, limiting machinery possibilities.
- Reactions stop due to mechanics (weight 0.18): Reactions halt when materials are stacked too much or when pressure mechanics are ignored. This disrupts gameplay flow and forces unwanted manual intervention.
- Controls and general roughness (weight 0.17): Players describe uncomfortable controls and a generally rough feel, which diminishes the enjoyment of the game.
- Lack of early access warning (weight 0.14): Several reviews criticize the absence of an early access disclaimer, as the game feels unfinished with only one planet available and many features listed as 'coming soon'. This leads to concerns about future updates and development commitment.
- Bugs and missing features (weight 0.12): There are bugs such as a mismatch between cooking screenshot and actual cooking. Overall, the implementation is lackluster with questionable design choices.
- Unbalanced mechanics (nitroglycerin) (weight 0.08): Players find it too easy to cheese nitroglycerin to create rockets that destroy anything, breaking game balance and reducing challenge.
- Recipes locked initially (weight 0.07): Some players want all recipes unlocked from the start to allow more freedom and experimentation, rather than having to unlock them through progression.

Gameplay feedback:
- Chemistry and reactions (weight 0.97): The game features a deep chemistry simulation with realistic chemical reactions, including heat, electrolysis, and interaction between elements like wood combustion producing charcoal and grass burning producing alkali. This system allows for player-driven experimentation and emergent complexity.
- Falling sand simulation (weight 0.65): The game is described as a falling sand simulation with real chemistry, pixel physics, and cellular automata, akin to The Powder Toy but more fleshed out. Players interact with a 2D environment where elements react based on physical and chemical rules.
- Automation and machines (weight 0.6): Players can build machines to automatically process ores, refine materials, and create production systems. Features include conveyor belts, furnace building, and reaction-based machine design, though movement is restricted to left-right on belts and vertical via freefall or gas buoyancy.
- Sandbox and survival (weight 0.55): The game blends sandbox mechanics with survival aspects, including exploration, resource gathering, and building. Players can destroy the environment, cut down trees, and deal with threats like acid rain while repairing their spaceship.
- Progression and unlocks (weight 0.43): The game includes a progression system tied to technology and materials, with unlockable items and tech tree progression. Players advance by mining, collecting elements, and refining ores to deliver to a spaceship.
- Resource and element collection (weight 0.32): Players collect and mix elements from the periodic table, including metallurgy and ore refining. Resources like rain can be harvested, and the inventory can hold any material regardless of state.
- Survival mode with enemies (weight 0.27): A survival mode is present with enemies and combat, requiring players to manage resources and defend themselves while exploring the procedurally generated planet.
- High replayability (weight 0.27): The game offers high replayability through multiple playthroughs, procedurally generated planets, and emergent complexity from the chemistry and physics systems. Regular content updates are also mentioned.
- Noita and Terraria blend (weight 0.26): The game is described as a combination of Noita and Terraria styles, with pixel physics, exploration, crafting, and combat elements similar to those games. It also mixes Gregtech-style mod with Noita's falling sand mechanics.
- Physics and pressure systems (weight 0.26): The game includes physics interactions between elements, mass and fluid dynamics per pixel, and a pressure system, though pressure may not function as expected. Heat radiates but does not conduct, and gases do not rise through liquids or solids.
