To make a star or fighter, touch your mouse-pointer on it while pressing space. To place it press p The yellow star gives you 0.1 energy. It costs $0. The green star gives you 0.5 energy. It costs $2 All the other things cost more and make more energy. You might have to press down very hard to get the blue star and/or the asteroids that are around a planetoid. Sorry... :P Use the blue and purple ships to fight off the pink ones!
