I’ll be entering again, using my usual C++ template code. I’ve slightly updated it since the LD17, and it now has configurable key mappings, in addition to: image loading; 2d drawing via OpenGL; basic GUI framework; audio via portaudio; a simplistic polyphonic synthesizer; and truetype font rendering. And it’s cross-platform, so I’ll be doing Windows, Linux and OSX versions of my game.
My dependencies are: GLEW; libjpeg; freetype; libpng; portaudio; SDL; SDL_image; SDL_ttf; zlib.
And I’ll probably be using some combination of Inkscape, Paint Shop Pro and Tracktion for my various audiovisual needs.
