For the past year or so I've been working with an independent game developer, Brad Carney, on a game called Wrack. I love working with indie developers. The music and sfx have been fun to work on, but they're not through. The game has been released with just three levels completed at this time. Those who support it now will get to watch it grow to 30 levels and will have input into further development. Brad included a user friendly map editor, and less than 12 hours after the game was released there were already some player made mods and maps.
