Point with mouse pointer and throw clicking. Depending on how far the mouse pointer is from the pistole, it goes with more or less power. Press "P" to paint, and "P" again to go back to the throwing mode. Pressing "E" you eliminate everything you painted. With the slither at the top left you change the planet / dwarf planet / satellite / star, and the other one (only in the Mystery Planet) you change the gravity.
