Hello, I appreciate your feedback. I want to make clear what you might not understand: according to the comments, the tutorial portion was created as a stand-alone tutorial because some players were having trouble grasping the game. Simply press the "skip" button in the upper left corner if you're bored and want to explore. "Use/not use" is similar to a test. There is a recipe that works with cards and hints, but there is also a switch based on difficulty; if you select medium, you have to change two switches from not used to used. There are one or three switch recipes, despite the fact that some recipes include cards and hints. Thus, you must locate two switches.
This artistic direction is unquestionably ours, not a bot's. Instead than looking at existing games and copying them, we want to create new things using our own ideas. Thank you for the idea.
