For those who don't understand the mechanics here's a explanation of the mechanics in the game:

Basic Mechanics:

you are in the restaurant's kitchen-you have camera system which you can look around the place, you have a gun which you can shoot with it, but the gun only has limited amount of bullets so be careful with it!, you also have a grill which you can raise it's temperature, and the most important thing in the game is: the chicken nuggets located on you desk.

------------------

Ross mechanic:

Ross is the weird gold chicken that can be seen in the cams, you can watch his movement but when he gets into your office shoot him!

------------------

Boxinugget mechanic:

boxinugget is the weird blue box, he will sit in the office window all night and will ask you to give him 10 chicken nuggets, you must do what he says or else...

------------------

Rotty mechanic:

Rotty is the weird little green rotten food found on your grill, you must heat the grill and he will not exit the grill, if the grill is too cold he will exit and kill you.

-----------------------------------------------------------------

That's the explanation of the mechanics, good luck!
