We need some art and sounds for our game reference app. I've looked around at some of the free art and there isn't much that would work for our game, but I'm sure there's other ones too. Soon I'll post links to free art I have found. I can whip up some pixel art, but it won't be extremely detailed and will take some time. Another option is to get a designer within Mozilla to help out.
See https://github.com/jlongster/webfighter/issues/12 for previous comments. jsocol's list of things we need art for: Player ship. Laser blast (we can simply recolor for enemy lasers, if we even want to). A floor/background. A dpad. A fire button. 1-3 enemy units (we can recolor). 1-2 power-ups, depending what we want to implement. Logo/wordmark/whatever?
This is done. I'm using this Tyrian set of graphics: http://hasgraphics.com/remastered-tyrian-graphics/
