GalaxyQuest is a simple dodge-rocks and get-jewels sort of game. Use the arrow keys to move your spaceship up and down, left and right. Try to collect the jewels, and dodge the rocks. In addition, you must also collect fuel cans to increase ship fuel, and collect hammers to reduce ship damage. Each jewel you collect will increase your score by 1 point, but coliding with the large rocks will damage your ship by 1.5 points, medium sized rocks will damage your ship by 1 point, and small rocks by 0.5 points. The speed of the game will increase every 25 points. The game will end either when you have no fuel, or your ship damage reaches 10.
