It's basically a kill everyone in an office or get killed by them, move with the arrows and point and click with mouse at enemy (everyone). I would give it a PG-13 rating.

Have you seen more like this?, share the links!

(Hint; hold the mouse down to focus the magnifier and drag it off the sides of the screen then release. If you do it correctly, it should stay focused when you bring it back to the middle and you can just wave it over objects without the need to hold the mouse button down)

Two more games I sometimes play with (click Pyroblaster or Digital Firework Stand) They are both themed for the 4th of July.
