Designing my game Part 3!!!

The third drawing is of the game itself. The basic object of my game is going to see how long you can last without getting hit and also how many points you can collect.
This is the drawing of my game:

 

The spitfire will be your plane and the Messerschmitt bf 109 will be the enemy plane i will be drawing the planes straight into flash and I really like vector drawing in flash. There will be a timer and a score counter in the game. 

In the background there will be clouds, which will be animated inside its own movie clip and this will give the effect the planes are flying past. The background colour will change depending on the time of your computer if its after 12 it will be Grey and if it is before 12 it will be blue.

The sound effect on this scene will be of a spitfire engine because that's your character.

The Spitfire will only go up and down also it will shoot when you press the space bar.

Down the bottom of the page i am going to draw some hills so it looks like a proper scene.
