I love these kind of management games, Icould spend hours on a game like this ^^
However, there are a few improvements you could make I think.
I would have appreciate to know what recipes I could unlock to know which ingrdients, actions and cooking methods to buy. I just bought them randomly hoping for a new recipe to be unlocked. That's very frustrating!
I also think you could improve the gameplay. I played for 4 days, and I still had just the burger and fries unlocked. And I just clicked on the ingredients, actions and cooking methods 10 times, no matter the order I was clicking on it, to make the dishes. My finger hurts now :D Maybe adding an order of click in it could be more challenging.
But I did enjoyed the time I spent on it. Good job :)
