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. Gentle contacts combine planets; glancing collisions bounce and hard impacts release material back into dust. Dust grains feed planets with small contact puffs. 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.
