I'm in for the 6th time.
I'll be using: Code: Love2d or Gamemaker:Studio depending on how ambitious my idea turns out to be. Art: Paint.net and possibly some stuff editors online. Sound: Rarely have time for it, sfxr if I get around to it.
First time doing the compo out of town. In Boston for a summer camp at MIT, but I may have even more time than usual because of that.
My small+terrible Love2d files I always use: https://github.com/thedashdude/LoveHelpers
Good for doing nothing, but okay at making buttons and collision detection.
