Particle Simulation

Paint & edit: Use Mouse/Eraser brushes and type buttons to add or remove particles. Drag to pan, scroll to zoom around the cursor, or use the corner zoom buttons.
Interactions: Click cells in the attraction matrix to tweak forces, pick presets, or randomize values. Increase or decrease particle types with the stepper.
Physics: Time Step, Momentum Keep, Interaction Strength, Interaction Radius, and Repulsion Core sliders shape how quickly swarms react. Choose Wrap, Clamp, or None boundaries.
Visuals: Swap shaders, palettes, and particle size to change the look while the simulation runs.
Saves: Export or import ZIP snapshots compatible with the desktop build. Settings save to your browser so you can pick up where you left off.

Left click increases attraction, right click decreases.
