Camera

 is a gun that deals damage to all enemies in the current room after a short charge up time. Also knocks back enemies and slightly slows bullets in the air upon firing. After firing the gun, sparkles appear in the air for a few seconds.

Bugs

 * Pausing and unpausing the game after firing Camera on a certain frame will freeze the game on a black screen. This, however, can easily be undone by pausing and unpausing again.
