In Orbit
While you are in Orbit, you must dodge the solar flares that are coming at you. You can shoot them if you want to by pressing the button while aiming in the direction you wish to shoot.
Activating Shields
If you want to activate your shields, simply pull the joystick downward while pressing the button. Be advised that using your shields costs you points. If you have no points you cannot activate your shields.
Landing on a Moon
While in orbit, you will come across a moon. To land on a moon, simply move into the path of its orbit and you will land. You can't land, though, if you are using your shields.
On The Surface
Your controls are slightly different on the surface. You can steer by pushing the joystick left and right, but now you can also control your speed. Push forward to accelerate and pull backwards to decelerate. If you pull back and press the action button, you can fire at enemies in the sky. Otherwise, your shots will hit ground targets.
Towers
Be careful of towers. They don't move and won't attack, but colliding with one will cost you a life and you will be returned to orbit. You can shoot them and you will earn points for doing so.
Miners
Miners are your primary objective here. While you are on the surface, a small pulsating indicator (for want of a better word) will appear below your score. This indicator will appear in various spots, indicating where the next miner will appear, so you can get your ship into position to pick one up. If you lose a ship at any time, all miners on board will be lost.
Launcher Ships
Watch out for Launcher Ships! These ships will deploy smaller craft onto the surface to attack your Moonsweeper. You can destroy both of them for points. The Landing Craft can not only shoot at you, but also capture miners, so get them fast!
Satelites
Satellites will fly across the screen from time to time, but don't attack. You can, however, shoot them and earn big points.
Leaving A Planet
When you have rescued six miners, you will be able to leave the planet. To do so, you must fly through the accelerator rings to get enough speed to leave. When you see one, fly through it and then through the next ones after to gain enough speed to take off. While they appear in a straight line on the Blue moons, the rest of the time, they will appear in a zig-zag pattern, so be careful. If you miss one, watch for another series to try again.
Game Difficulties
There are four different colors for the moons that you will encounter, each one representing the difficulty of that moon. The higher the difficulty, the fewer miners and more enemies there are
The four difficulties are:
Blue: Easy
Green: Moderate
Yellow: Hard
Red: Very Hard
The odds of seeing different moons are based on the game variation you choose:
Variation 1: Blue and Green.
Variation 2: Blue, Green, and Yellow. (Mostly Blue and Green)
Variation 3: Same as above except it's mostly Green and Yellow.
Variation 4: Blue, Green, Yellow, and Red.
