Once you have clicked the green flag to start the game click q to aim your gun. Aim of the game: You have to sink the ship by shooting it. To shoot press space. But you can only shoot if the safety catch on your gun is off, hold down q to turn off the safety catch. Difficulty: To make it harder press the 'up arrow' and to make it easy again press space. See how high you can get your score!
This is my first game so don't be prepared t be amazed. Bugs: 1) The ship does go backwards, but I will try and change that. When viewing your score, sometimes it keeps changing. 2) When you put the difficulty on hard the ship teleports forwards.
