Try to challenge yourself while you are an aeronaut of an orbiting station. You have to build solar batteries on the flying station or you will be dead. This honorary mission will challenge you and you should rely on your logic. Advanced 3D visualization and modern music will distract you, but you can turn it off to keep energy of your thoughts. The commodore will be pleased to help you in demo mode.
