Before detonation, supermatter pulls all objects, including anchored objects in a 13-tile radius (just enough to cover the control room) towards it for 10 seconds. Windows within this radius are immediately shattered.

Supermatter no longer pushed around by airflow.
Unanchored objects and players without magboots are pulled twice as fast towards the supermatter.
Supermatter shards have a smaller pull-radius.

Leftover variable removed.

Supermatter becomes anchored when detonating, and is hence not pushed by mobs than gib against it.
Detonating supermatter immediately turns the zone into vacuum.
Spam from objects disintegrating against detonating supermatter removed.
Pull radius increased to 14.
