I'm not entirely clear on the goal, but the art is adorable!
Use the arrow keys to move your ship, Up activates thrust, Down decelerates, and Left/Right turn your ship. Pick up asteroids with your spring to pull them around, and press space to release them. There are 4 springs to find in total. If you want to drop a spring, press P. Sometimes springs will grab asteroids on their own, making them harder to find. Look for asteroids on planets that are behaving oddly to find them. If an asteroid turns red that means that its orbiting a planet!
