First, sorry my English.
Second, beautiful Freddy.
Third, You can add a visual feedback to know that child is selected, a outline purple maybe, and then add other visual feedback in empty tables.
Would cool if you make the food, so deliver food is bored. Ingredients can spawn in table and then you marge him to make food, or the ingredient can spawn in a belt and then the player can stored him in table to merge later, this makes your game more interesting in my opinion.
Change font for a most pixelate would good too.
