not impossible, all its going to do is kill the bricks then the brick physics do the rest.
the black hole sucks the bricks.
also.. the creater should make it so the bricks aren't just gone forever.. should be that they respawn (but not normal time (it's cooler if longer)
maybe.. 8 or 10 seconds and then they respawn :)
(if someone can make it fulltrust)
and it's not impossible.. it just takes a [little] bit more codes
but that's not much for the people who can make really cool things.
