The aim is to mine all the jewels in a level, the jewels are hidden inside of the asteroids. Drop off humanoids onto the planets surface where they will walk along the surface collecting the jewels, you can also pickup the humanoid and transport him to another part of the planet. The more jewels a humanoid collects the better the powerup/bonus its able to give the player when its picked up.
Alien's teleport in ever increasing numbers in order to try and stop you. Keep an eye on the countdown which will tell you when the next wave arrives.
With each Alien and asteroid destroyed a number bonus will be created, which the player then can pick up, the numbers will change colors every few seconds, collect enuf of a certain color and you can upgrade your spaceship, you have to be quickish to collect the numbers or else they will explode when they reach the ground.
