My first ludum this year!Tools of choice:
sfxr/Audacity for sound, jcgmusic for music, Gimp for graphics. I'm going to use Java and LibGDX and good ol' trusty IntelliJ IDEA for my programming.
I am currently working on open sourcing a game engine I have made for ludum: ludum-engine (demo)
I won't be able to provide much support for the code during the compo, but if you want to take this engine for a spin you are welcome to!
Look at the game demos in the video stream to the right to show some of the engine capabilities!
