Javascript HTML5 Delta Game, JavaScript Shooting Game
=================
This is a small weekend homage to the classic c64 shoot-em-up "Delta".

TODO
=================
- POWER UPS
- speed
- fire rate
- fire multiple
- fire up/down/back
- shield

- MORE ALIEN VARIETY:
- rotate around a queen alien
- pillars with gaps to fly through
- boss aliens
- split/multiple waves (e.g. 2 or more independent waves at same time)
- ddx/ddy accelerating (hyperbolic and elliptical motion)
- give aliens customizable health so they might take multiple shots before dying
- give aliens customizable shot rate

- MORE GRAPHICS
- alien graphics
- bullet graphics
- rock/border graphics
- title screen graphics

- CLEANUP and MISC
- clean up the hideous N^2 collision detection code
- use a little PUB/SUB event handling for simpler code
- "are you sure" confirmation on quit
- high scores
- performance (avoid garbage, optimize rendering)

DEVELOPMENT
=================
The game is 100% client side javascript and css. It should run when served up by any web server.

Any changes to the following files will be reflected immediately on refresh of the browser

- js/delta.js
- css/delta.css
- images/
- levels/

However, if you modify the js/game/ or js/vendor/ javascript files, the unified versions need to be regenerated:

js/vendor.js # the unified 3rd party vendor scripts (fpsmeter, state-machine, etc)
js/game.js # the unified general purpose game engine

If you have the Ruby language available, Rake tasks can be used to auto generate these unified files:

rake assets:create # re-create unified javascript/css asset files on demand
rake assets:server # run a simple rack server that automatically regenerates the unified files when the underlying source is modified
