your mission is to get as many scores as possible while collecting stars. In the game, you don?t need to shoot, and all you need is to aim your enemies. You can navigate your aircraft around by using arrow keys. Try to destroy enemy energy cubes before they hurt you. You have to collect 10 stars to trigger the 11th star which means you will meet the boss. Of course you will have a harder fight against the boss, but hold on. You can win this battle. Good luck!
