Cook (SimBurgerKing) is a very simple game. Press the button that is represented by the icon onscreen.
Note that it is very much a work in progress: it was originally designed for Bung 2001, but I'm not a very good time manager, so I ran out of time. I just wrapped it up this final night, just to enter something. :) (That's why it's named bungcook in some places.)
