You have crash-landed on a hostile planet and now you need to do repairs! Use your arrow keys (or your W, A, S and D keys) to move about the planet. You also need to use your left mouse button to repair your ship. Also you can use your space bar to choose your weapons. On the bottom of the screen you can see the repair meter and you can see how close you are to getting your ship repaired and ready to fly. There are lots of enemies that are coming after you.
