I liked this very much! Everything was clean and intuitive and worked well. The art was lovely and the tactility of the minigames to grind ingredients and cook the potions felt great.
I would have liked to see something more to do during lulls when you're out of potions to cook / ingredients to grind, but as somebody who has worked on games with similar systems in Godot before, I know how it takes so much more time and work to get these mechanics working properly than you'd think, the back end of inventory/crafting systems and such is very time-consuming. Maybe something for a full version if you pursue it!
In any case I definitely think you have something cooking here, no pun intended, and I think a fully-developed version with more features and polish could be really great! Nice work!
