So I am in again. It´s gonna be my second LD and I´m really looking forward to the weekend.
My setup will pretty much be the same as last time with only some minor changes due to “lessons learned”.

Language: Java
IDE: Eclipse
Librarys: Libgdx, Artemis, Box2D, Box2DLights
Music and sound: SunVox and sfxr
Graphics: OmniGraffle, Paint.net and Tiled

I will probably use some base-code I came up with after last LD, mainly some convenience classes for easier management of collision groups and Mouse/Keyboard input handling.
It can be found here here.

Good luck and have fun to everybody!
