Space+Invaders

This was written for the Atari 2600
 * Which platform is this game written for?**

This is one of the most classic games that everyone knows. You are a space ship trying to defend earth from an onslaught of aliens that move in rows and move faster the farther you go. All you have is a gun and two shields to fight against an invasion from Space.
 * Give a 1-2 paragraph description of the game. (Suppose I'd played all the games but didn't know their names - how could I tell which one you were talking about?)**

I might need stuff like: playerShip, playerBullet, enemyFirst, enemySecond, enemyThird, enemyBullet, shieldOne, shieldTwo
 * If you were to write this game in Flash, what sorts of symbols would you need?**

I would need an array for the rows of enemies so that they would move together as a unit. It would probably be divided by rows and each row would be programed to move a certain way. I would also need it for the bullets from the player and enemies because they need to be able to be fired rapidly, code similar to the Asteroids game.
 * If you were to write this game in Flash, what things would you want to keep in arrays? (e.g., an array of all the things that animate, an array of all the player bullets, an array of the obstacles, etc.)**

I might need again a bunch of tracers showing that the things are working and stuff of that sorts.
 * If you were to write this game in Flash, what things would you need to test every animation to see whether they have interacted? (e.g., each playerBullet vs. each Enemy.)**

I think that it would be about a 6-7 because of the arrays that would be needed for the aliens would be the most difficult thing along with having them speed up and firing randomly. Also having parts of the shield disappear when hit would be challenging, but moving the player is the exact same is in the Rubber Chicken game I made, except it is on the bottom of the screen not on the side.
 * On a scale of 1-10, how hard do you think it would be to write this game? Explain.**
