I'll be writing updates on my progress (when time allows) as the challenge is underway, and you can see all related posts by viewing my Journal category labeled "Community Challenge". I also have an album where screenshots of my entry shall go. (Currently empty, since the challenge hasn't started yet).
For my project, I'll be using C++ with SFML as the 2D graphics API, using the QtCreator IDE, and compiling with the MinGW port of GCC as my compiler. Depending on what I decide to make once the theme is announced, I may also use Lua in my project.
