I want to make a game, Right now!

So tonight I will be making a game. I have a relatively simple idea and thanks to 2DBoy's rapid prototyping tool Im going to make it right now!

The game engine already comes with an Asteroids clone and Im going to modify it to fit my needs. Im going to approach this game with rapid prototyping in mind. I'll start with an initial idea and iterate on the gameplay until I have a solid game. I will also be accepting any suggestions to my design idea.

Super Spaceteroids

Asteroids is usually a solitary game, however I wondered how it would be like if it turned competitive. What if there was another player who was also competing for points. Maybe the competition can go deeper, maybe there is a story behind it. Maybe they arent even really shooting asteroids, it may just be an abstraction of a larger picture. Nonetheless, the base gameplay is to have two ships, a computer play and a human player competing for the number one spot.

Tasks:
Computer AI
Two ships on screen
Score for both players
Win/Lose Condition
