Brief update for the GDNet+ journal: I'm about three days into my week, which has mostly been spent familiarising myself with the tech. I've assembled a very basic functionality set from old projects of mine, built on top of SDL, OpenGL, PhysicsFS and probably several other libraries I've forgotten right now. It's basically a gutted half-completed game layer tied together by a thousand hacks, but it does all the basics and is "prototype-ready".

All I need now is a game idea. And that's proving difficult.
