I started out making a Galaga clone but decided to do something a little different. I'm calling it Galagan Arena.
It's sort of a combination of Galaga, Asteroids, and someting else... idunno:

Use the left/right arrow keys to move around the ring. You can use the up/down keys to move closer in the loop but I found that while playing it really didn't come in handy, it's still there though.
Control key fires.
There are challenge modes every couple of stages. You get a bonus if you kill all the ships in the challenge mode.
You have five lives per stage. Your ship has a "shield" that weakens when your shot or run into an asteroid. The shield strengthens with every enemy kill or asteroid destroyed.
Every 12,000 points you get a bonus ship with "rapid fire"... you'll see what I mean.
The first few stages are pretty easy but things start to speed up really fast in the later stages. I can only get upto 9.
Hope you like
