Let's go ! Customers arrive at your shop and order potions of different values ​​from you. To make the requested potions, you must mix the ingredients at your disposal using one of the laboratory machines. Each ingredient has a value and each machine applies an operation predefined on the ingredients that you present to it. Between each round, you can spend your points to improve your laboratory. Each improvement increases the difficulty (new operations, curses, divisions, storm, negative numbers etc.) but also the number of points you will earn by fulfilling orders. Don't be too greedy, or you risk overheating your brain and your controller!
