Oh my, that's a lot of different recipes. I want to come back to this later with more time. Combination games are pretty fun! Especially when themed like this. I would say the non-safe combination sound is a bit jarring.
I wasn't able to get too far because of a black key. I had no idea how to make it. Perhaps I needed to find a different solution. The main difficulty I see with combination games is finding combinations that makes sense. Sometimes you just can't guess or combine the right items for a black key.
I do want to come back to this though. It just takes time to discover combinations and recipes.
