What a great fun concept, looks like it was a lot of fun to work with. I liked the artstyle a lot, although I think the doors have to be designed wider, because the opening is hidden by the graphic of the extruding wall, so you have to rub your face against the wall to find the opening. A tutorial wouldn't hurt either, even though there are only two methods of preparing a human, but through trail and error you figure it out. Also, when failing a customer's order, their failure text still remains floating in the air afterword, making it hard to continue if you fail the first time.
Regardless, it is a really unique idea and fun reprieve. Good job!
