X-Shooter [Color Wars]

I'm in the process of redoing all of my old games in order to update my portfolio, so I started with X-Shooter. The game is being used as a tutorial for a game development club--a base to build upon and expand further for beginners, so it's nothing too impressive.

You are defending a barrier against an invading army of enemy ships, attacking continuously.

*Use the "Z" key to fire and "X" key to use your color bombs.
*You can only move up and down.
* If the barrier takes ten hits or you take three, game over.
