I’m in for the first time, getting more excited by the minute! I’ll be using Flash as I feel most comfortable creating things fast with it.

So: Flash Pro CS5.5 + Gimp + Bfxr.
Code will be made all from scratch, except for a small, sleek Keyboard-Control lib (Input.as) by Matthew Bush (sourceforge.net/projects/box2dflash/).

Good luck and lots of fun everyone!
