Click a letter to turn it into powder. Drag the sun to move its gravity well; consumed material grows and changes its color. At critical size it swallows the asteroid and remaining material, then collapses into a supernova. Close, slow dust condenses into solid planets with one pixel of area per grain. Drag a planet and release to throw it. Double-click a planet to disintegrate it. The planet button toggles solid planet formation in stage two; switching it off returns planets to dust. Gentle contacts combine planets; glancing collisions bounce and hard impacts release material back into dust. Slow dust impacts feed planets with small contact puffs. Fast grains deflect and excavate planet material into dust. Larger planets become unstable and split. A sufficiently large planet ignites into a new sun, grows as it consumes surrounding material, and repeats the supernova cycle at critical size or once all material has been consumed. Pointer gravity is active only while the mouse is on the canvas or a finger is touching it. Hold empty space to pour particles with a wide brush; the dust stage pours more slowly. Dragging throws grains with the momentum of your movement. Arrow keys move the brush; Enter interacts. D disintegrates all letters. L restores the letters and platform while keeping the sun. R resets everything. Space pauses.
