I am in for the 6th time!

Language and Library: Java Swing, or LWJGL, for a change maybe

Graphics: Paint.NET,  Piskel, maybe Inkscape and Synfig

Music: LMMS, maybe incompetech.com, Abundant Music. Depends on how much time I have left

SFX: Might use SFXR if I have time or just Audacity.

Cannot wait!
