I laughed at the concept of you being the one in charge of _where_ to heat microwaved food. Nice concept.

That said, I liked the implementation, seems simple enough to understand what your actions affect. I'd probably say that the strategy falls a bit short, since it's very easy to find how to "win" each round, by simply trying to distribute the heat all over.

How about a defectuous microwave that changes the amount of heat or the cover area? or someone leaves a fork inside? ;)
