So, the basics:
Audio – Lmms and others free procedural generator sounds that you can find here http://www.ludumdare.com/compo/tools/

Engine – Still thinking, maybe Godot or Unity 3D, if so, I will use all my previous entries as reference material

Graphics – Krita, Blender, Gimp

I think this is it, if I use something else, it will be very explicit that was added.
See you guys there! 😀
