I've been making games for a few years now as a hobby, and entered game jams such as Ludum Dare and AGBIC. Most of the games I've finished were made for various game jams as I'm often too lazy to polish any of my prototypes and put them online.
I started with SDL and have moved on to web stuff using Dart and WebGL. Recently I wrote my own engine called Corium using C++ and OpenGL.
