Good art and controls. I think there's an interesting idea here, but I'm struggling to connect the information in your tutorial to the game itself. I cannot get past the first customer.
Did you perhaps miss the "minimum required ingredients"? This is shown as the ingredients in a black box in their dialog? If you manage to do that, you should be able to pass every customer, everything in the tutorial is just *how* well you want to pass it!
I seen the ingredients in the customer dialogue and used them. My main confusion came from the tutorial (attempting to interpret what "appropriate heat" I needed), I've given the game another go since the update to play in browser, and was able to make it through the customers.
