Well it is indeed easy for it to spiral out of control! quite some mechanics to control, but that's nice because it makes you want to play again, and again, and again. nicely done and I love that everything from art and audio as created yourself.
A small addition that could be nice is some sort of voice that tells you what the next item is. That way you don't constantly have to look what the next item is and you can focus more on matching types of sweets and managing the factories.
