I’m going to give this a shot.
Gimp / Inkscape
SFXR / Audacity
Flex SDK, nano, make – that’s right CLI flash development unless I change my mind and use C++ and SDL.
Here’s hoping I manage to complete something!
Edit: My simple flash boilerplate if anyone is interested. It’s basically a preloader, simple menu, and resource loader. – ffw.tar.gz
It includes greensock tweenlite, everything else is MIT/BSD, whatever.
