A relaxing particle physics sandbox
Goal: Paint elements onto the canvas and watch them interact with realistic physics. Sand piles, water flows, fire burns, plants grow, lava melts — and things explode.
Elements: Sand falls and piles · Water flows · Stone is solid · Wood burns · Fire ignites · Oil floats and burns · Smoke drifts up · Steam condenses · Acid dissolves · Plant grows · Lava melts stone to itself.
Advanced elements: Glass forms when fire or lava heats sand · Ice melts near heat · Metal is fireproof but melts in lava · Salt dissolves in water · Gunpowder explodes on fire · TNT makes big booms · Wall is indestructible · Void swallows everything it touches.
Controls: Click or drag to paint. Right-click or the Eraser removes elements (sandbox only). Undo reverts your last stroke. Speed up to 2× for fast reactions.
Challenges: Solve 16 physics puzzles with limited elements — each stroke has a paint budget (watch the cells counter) and the brush is capped, so every drop counts. Some levels demand you protect a structure while destroying another — let it break and the challenge fails! Fewer strokes = more stars.
Sandbox: Free play with every element — your scene auto-saves; load a Scene preset or build your own. Achievements unlock as you experiment.
