Potion seller, I need your strongest potions!
I like how the longer animations for putting ingredients in push you to find recipes that contain less ingredients so you can make them faster for a bigger bonus. Even though the option is there to add the correct ingredients one by one, players who want to get the best score can find the fastest combinations.
During my playthrough, I forced myself to try to find better combinations beyond just adding the basic ingredients to engage with the mechanics more. Perhaps having a little pity bonus for not exclusively using the basic ingredients would be nice.
The dialogue is fun, and I especially love the ending.
