I'm assuming the breakable bricks in the intro to your video are just multiple circle particles attached to eachother? Can you share some insight as to how you implemented this?

This project with breakable objects is based on a completely different method (it is an impulse based solver, not position based). The only common point is the use of circle as "atoms" to ease collision detections.
