Thanks for playing kryione!
One of our concepts was for the player to remember the recipe as the game progresses such that they no longer have to refer to the order sheets, but I think we got carried away with the number of recipes as it was quite fun to come up with them haha. It was impossible even for me to recall what ingredient goes where after a while. Allowing upgrade by using tips would indeed be a cool feature! Might even open up potential for purchasing of new ingredients to make new drinks possible. Thank you for your feedback!
