Overgod 1.0

Overgod is a 2D shooter with multiplayer support based on Allegro.
For too long has humanity been ruled by cruel and disputatious gods! Fly through the various layers of the Celestial Oversphere to unseat those who control the universe.
This is my latest game, Overgod. Its similar to my last game, Lacewing, but better in almost every way. Basically, you control a little vehicle in the middle of the screen and fly around and shoot things - a bit like asteroids, but the asteroids move independently and shoot back. You can also upgrade your vehicle in various ways.
Main features:
- Over 100 different enemies
- Lots of randomness and chaos
- Various different modes and unlockable challenges
- 1 or 2 players (splitscreen)
- Pretty low system requirements (about 300MHz is plenty, and it doesnt need any kind of fancy graphics card)
- Days of fun!
It should compile on any platform supported by Allegro. Windows and Mac binaries are provided at the moment, as is source code (its under the GPL). The links are all to sourceforge, which is a little cumbersome, but for various reasons Im releasing this through Internet cafes and the Library so thats what you get. Have fun!
