Glad you enjoyed it.
To create food you need to assemble dishes out of raw ingredients which can be found when your talking cover,(holding down space) .
Your current held ingredient can be found in the top left of the screen.
Placing a correct ingredient in the correct order gives a green tick and placing a wrong ingredient gives a red cross and ruins the dish.
If you place all the correct ingredients of a dish in the correct order you will get the finished product and score is then added.
