Orb Eater has you flying through a ship over planet earth. The images of earth are very realistic and make a beautiful backdrop for the game. You'll have a cursor in your screen that you will run over different colored orbs which you will collect. Some orbs make your cursor smaller or bigger. This can come in handy when you start getting a lot of red Xs or orbs that are not good and you can't avoid those with the big cursor. Some orbs will give higher points, especially if you collect the same color at the same time. You'll level up after a certain number of points, but don't collect too many red Xs or you'll be done!
