Nice idea, and fun idea to control grill deposit of a computed and automated operating system. I did not sure how to heat the meat (spacebar?) and i tried first to stay on hellhole by the grill. I found then a strategy to make a switch to make delivering fast by switch to first person mode and take order and brake back to kitchen by using only wsda keys.
This would be an awesome multiplayer also, with ability to change between robotic machines (like to grill, deep fryer, microwave, etc.) Camera position changing is quite unique too and makes it feel like monitoring the whole station.
