Pixel Rain

Paint pixels. Watch chaos unfold. Pixel Rain is a relaxing falling-sand physics sandbox where every cell on a giant grid obeys its own rules. Pour water, drop sand, ignite lava, grow crystals — then sit back and watch it all interact. There's no campaign, no fail state, no pressure. Just you, a canvas full of physics-driven pixels, and a lot of satisfying emergent behaviour. Hundreds of Materials to Paint With - Sand — piles and settles naturally - Water — flows, pools, and reacts with almost everything - Lava — turns water into steam, melts ice, ignites everything nearby - Acid — slowly corrodes stone, metal, and crystal - Oil — floats on water, highly flammable - Crystal — grows from water and ice into spreading formations - Plant — feeds on water and spreads organically - Plasma — decays into sparks over time - Void — silently erases everything it touches - Magnet — pulls nearby metal cells toward it - Plus: Paint, Slime, Foam, Snow, Ice, Smoke, Spark, Stone, Metal - …and 400+ more — from concrete, salt and sawdust to charged crystal, living wood and brimstone. Combine any two materials and you might discover a brand-new one. Features - 60 FPS physics simulation on a dynamic grid up to ~620×480 cells - 400+ paintable materials and brush presets with scatter, sparkle, and jitter tuning - 6 customizable quick-slot brushes - Adjustable gravity, flow speed, brush size, and zoom - 3 procedurally synthesized music modes: Rain, Magma, and Aurora - Procedural sound effects keyed to each material — no audio files, all generated in real time - One-button MP4 clip export (R to record, R to save) - Showcase cinematic mode (T) — the camera finds the most active region of your canvas and records it automatically - Save and load your canvas, synced across devices with Steam Cloud - 100+ Steam achievements with progress bars and in-game toasts - 50+ discoverable recipes — combine two materials to alchemize a third - Steam Workshop — design your own materials, brushes and animations with built-in editors (plus a DevMode code editor), then share them and subscribe to community creations - Built-in tutorial to get you started - Custom color palette and lobby theming Early Access Pixel Rain is in Early Access. The core simulation is fully playable and stable. Expect new materials, brush tools, and quality-of-life improvements as development continues. Feedback welcome.
