Knee deep in improv….
This is my first LD entry, and it should be lots of fun, or at least very interesting!
I was thinking of possibly using C#/XNA, but I recently decided I will be coding in C++ instead. As a result, I’ll be using a new framework I started writing only a couple of days ago, and a bunch of other libraries of which I have little or no experience using. So the goal is to keep it simple. 
In a short moment we’ll all know the theme, at which point I can start pondering on the gameplay. Lots of improv (and learning) ahead!
Libraries used: SFML, OpenGL, boost, Eigen, and possibly lots more.
