Make your way to the right, to the green wormhole. Do not touch the Sun. On a planet: right-arrow walks forward, left-arrow walks backward, up-arrow jumps. Moving is tricky because up and down depend on where on the planet you are standing. In space, gravity controls you. If you sail off into space, wait half a minute and gravity will pull you back. Or you can press "r" to restart the level. Every level is possible.
