Zen Toroid Mechanics

• Click / Touch Attract particles (Gravity).
• Ctrl+Click / 2 Fingers Repel particles (Anti-gravity).
• Scroll / Pinch-to-Zoom Add or remove particles. Mass is perfectly conserved otherwise.
• Collapse & Growth 5 particles of the same color gathering tightly collapse into a Black Hole. Black Holes absorb their own kind to grow and violently repel the opposite color. If a hole starves, it melts back into particles.
• Collisions Identical Black Holes merge. Opposite ones annihilate in a massive Big Bang.
• Overgrowth If a Black Hole grows large enough to touch itself across the Toroidal space boundaries, it triggers an instant collapse.
• Toroidal Space Particles crossing the screen edge teleport to the other side and invert their color.
• [Space] Resume / Pause simulation.
• [Esc] Reset the entire universe.
