Conway Extended 🔬 — Advanced Cellular Automata

Tools: Brush (click to paint), Line (click start→end), Rect (drag), Fill (click to flood), Eraser (right-click), Clear grid, Random fill, Place patterns.

Rule Presets: Conway B3/S23, HighLife, Seeds, Maze, Replicator, Diamoeba, Annealing, 2x2, Day&Night, Morley, Custom via text input.

Multi-Species: Up to 4 species with different colors. Species compete for space — birth requires species-specific neighbor counts.

World Types: Toroidal (wraps around), Finite (hard edges die), Reflective (mirrors at boundaries).

Neighborhoods: Moore (8 neighbors), von Neumann (4), Extended (24).

Color Modes: Species-based, Age-based (rainbow by generations alive), Heatmap (frequently alive cells glow hot).

Pattern Library: Glider, LWSS, Pulsar, Gosper Gun, Block, Blinker, Toad, Beacon, R-pentomino, Diehard, Acorn, Pentadecathlon. Shift+click to place.

Controls: Space = pause, H = help, 1-9 = speed, Arrow Right = step one generation, R = random fill, C = clear, [ ] = brush size.
