I downloaded your example but I suppose there's something wrong. Was it perhaps made with an older version of Scirra's C2?
I suppose I would have seen something like a necklace or a chainsaw made by several "link" object kept together by physics. Is it correct?
I'm actually playing it on a Beta r101 and when I start the layout I can see 30 black links raining down without any link between them.
Is something changed in physics management in this last release?
Thank you: I need your experience to understand better C2.
