I love Asteroids!

Asteroids was one of my favorite games growing up.  A little while back I got to play on an original cabinet with real vector graphics.  What a treat! 

I posted this game because I would like to develop it further -  Perhaps into an RPG or Roguelike?  If you think the game is fun, please let me know how you think I should expand it?  Any feedback will be appreciated! 

The tutorial I used to make it has been updated, and I plan to go back and see what it has to offer and post the updated version as soon as it's functional.

Features I am hoping to add in the short term:

     - Enemy ships, friendly ships

     - Weapon power-ups (Laser, 3-way, rapid)

     - Colors? - I want to keep the pseudo-vector look, but I think colors would look nice.
