Can't wait to figure out the theme! It'll be my first Ludum Dare. I'll be using UPBGE!

It has a bad rep for no reason, really, because while Logic Bricks are limited Python can take it so much farther. I'll be using Logic Bricks to help speed up the dev process though.

Other things: Blender (with UPBGE), Inkscape, Audacity/Ardour/LMMS, Krita probably, GIMP. And who knows what else I have hidden on my computer in the depths of Program Files that will come in handy!
