I was curious if there is a way to increase the rigidity of arcade sprite bodies. At the moment, they seem to overlap quite a bit, and even fall through each other at times. You can see in the gif below (and demo) that a whole row gets lost.   Is there any way to completely get rid of this overlapping/fallingissue? If yes, can it be done with arcade physics, or do I need to switch to ninja or p2?   Demo of issue here: http://codepen.io/jackrugile/pen/0309643b449e772eba93fc9be3c8e7be/
