Game Summary - "Phase 1"

So for phase 1 of the game here is our checklist of objectives.
1. Basic game flow which includes: logo screen, splash/title screen, how to play pop-up window, game screen, game over screen.
2. Game play will be a left-to-right, ship side scroller. Player movement will be limited to predetermined area of the screen. There will be only one 'layer' of scrolling background.
3. Player has a single fire weapon which fires in the direction the ship is facing.
4. There will be one type of enemy and it will spawn at random heights on the right side of the screen and move to the left.
5. Play time will be limited by an 'air supply' that the player's ship has. The game is over when the player runs out of air.
6. The only player pickup will be tanks of air that spawn at random intervals and move along with the background.

So, not the most original of games, but it's a start and one that can be expanded on once the basics are laid out.
