Well, I started using it, but I found it was very hard to understand due the lack of good examples..
Also it was hard to add custom bodies to the world and then use dragging etc.

But the most important thing is that the thing I'm working on is also rated for the code, so if I write it myself, they will probably be more generous ^^

I'll try the parenting and matrix transformation and see which one works

Thx in advance!
