Mixie: Falling Sand Sandbox

Mixie is a relaxing physics and particle simulator where every pixel reacts realistically. A pocket laboratory to experiment with science, thermodynamics, and your creativity.

Mixie is an interactive sandbox (falling sand) where gravity, chemistry, and temperature create a world of emergent possibilities. From small chemical reactions to massive explosions and electrical storms, the power to create and destroy is in your hands.

Experimentation & Alchemy
Start with basic elements like dirt, water, and fire. Combine them to discover a catalog of over 40 unique materials. Boil water to generate steam, freeze it to make snow, mix acid with alkaline water to get salt, or melt sand to create glass. Every interaction helps you discover new hidden recipes.

Realistic Physics & Thermodynamics
Mixie's engine simulates the authentic behavior of matter:

Thermal Simulation: Heat transfers naturally. Molten metal glows, wood burns to ash, and ice melts.

Fluid Dynamics: Liquids flow and mix based on their density and viscosity. Watch lava melt through stone or mud bake into solid clay.

Gases & Weather: Steam rises, acid gases condense, and dynamic storms can generate lightning strikes that interact with conductive materials.

Living Ecosystems
Plant a seed in moist dirt and watch nature take over. The procedural growth system generates trees with branches and leaves that react to their environment. You can cultivate a thriving, complex ecosystem or watch a forest fire reduce it all to ash.

Chaos, Destruction & Radiation
If you prefer action, you have the tools to unleash controlled chaos:

Experiment with gunpowder and metal to engineer your own bombs.

Harness radiation from lightning strikes, transmute ores into glowing uranium, and watch as it autonomously generates intense heat.

Trigger massive, screen-clearing explosions to wipe the canvas and start anew.

Challenges & Creative Freedom
Draw with your fingers to create incredible landscapes or complex thermal machines. If you ever get stuck, the mission system will offer engineering challenges (like building specific explosive containers), and the smart hint system will help reveal the secrets you need to unlock.
