Spaceship video game

Our game that we made is a spaceship game. The player is able to move the spaceship horizontally and is able to shoot lasers to the incoming comets and bombs. The comets and bombs are created at the top of the world and travel vertically toward the spaceship. When the comets and bombs are close to the spaceship, the game is terminated due to the strong radiation that destroys the rocket. The game is started by the player pressing the "space" key.
