I haven't done a Ludum Dare in at least a year, so heeeaaarrr we go! I will be using

Unity with C#, Visual Studio, Audacity, LSDJ running in a GB Emulator, GIMP, ASEPRITE (maybe), and Creature Animation (if needed).

I've got my core idea down, but needed to knock out some basic art before I can start scripting behavior. I don't mind doing it, but I'm pretty awful. I try to work with primitives when I can, because I can't draw. Here's a bit of what I was able to get done tonight, using GIMP and Creature Animation. I'm going to get some sleep, and start making gameplay happen in the morning.
