In case anyone was wondering (I know there are some lurkers 'round these parts) I have still been working with Love2D and Lua. I'd like to get LightMaze to the point that you can play it start to finish like a proper game. I have some other things in the works, though, as usual...
I was lucky enough to get Voxatron with a Humble Bundle and it turns out I now also have access to this lovely tiny indie game maker, PICO-8. Their front page describes it better than I ever could so check it out! The limitations do inspire people to make some very creative programs.

Oh yeah and this is like the coolest toy I've ever seen, the physics let you actually paint smooth-looking strokes:
