A nice little stategic game. Is it action orientated or is it a puzzler? It's a bit of both. Fly your spaceship from one base on a moon to another. Not as simple as it sounds as you have limited fuel and must deal with the unpredictable gravity of the moon. As always, a simple premise which makes a nice little game.
Practice is needed to really understand the pull of the moon's gravity. Also stay as close to the moon as you can, if you drift out too far you will find yourself in a lot of trouble.
