Thanks for the review ^^
We were thinking about an upgrade system at the start but didn't manage to find the time to implement it
We were thinking of a system similar to Papa's games where you would unlock new recipes as days went on and customers would leave tips based on the time you took to fill/take their orders allowing you to buy more appliances
But this turned out to be way too much for just 3 days for us
If we continue it (which I think we will) this and the highlights will definitely be on the list of things to add
As well as more customer variety
Glad you liked it anyway :)
