I must admit, the tutorial image left me more confused than not, good that the game itself is pretty simple to understand once you start playing. Then again I have played restaurant tycoon games before, so the concept is familiar.
I like the theme and the execution of it, although not sure what I think of the sewer monster. But then again, the customers are so forgiving for getting more than they asked for, so I guess there had to be something to threaten the "business" (especially as you cannot exactly go bankrupt). :D
I personally felt that the stacked blocks were not that intuitive, but maybe I just prefer the traditional icon-based food games.
