The art is very nice and the drag and drop for the baking works well. I think having a bin to clean up mistakes would be a good idea, i made a lot of burnt things!
The other thing I had trouble with was that if I dropped a baked item in front of the ingredients I then had a lot of trouble picking it up (I kept grabbing more ingredients instead).
I liked that the customers were patient and I could get their items made even when I was clumsy :)
