I'm CNIAngel. Artist/Programmer/Triangle guy. I've made a few games in my time as a programmer and libGDX has been the most important part of it so I'm looking forward to this jam.
Code: libGDX+Eclipse with some boilerplate code for simple sfx, sprite, and scene management.
Sfx/Music: SunVox & LabChirp
Misc(based on theme): Tiled, Assorted libGDX tools like the Paticle Editor and such.
Looking forward to seeing what everyone does for this jam. I'll make sure to clean up my code before I post it :P
