This is a beautiful game! The art is gorgeous, and I feel like you have put in a lot of effort in drawing good-looking assets! Kudos for that! The scope of the game seems very large for a single person in just one week. There are quite a lot of recipes, and all of them have an associated potion and client! That really a lot! it has to be said that it's very well done making all these stuffs and successfully combining them into a working game! The gameplay loop is also nice and fun too.
For some criticism and suggestions, I'd say the input and ui of the game leaves a lot of room for improvement. I think the game will be much better if there are more keyboard controls and possibly ditches mouse input altogether. Things like opening and closing dialogue boxes would be better controlled via keyboard controls. Some keys, namely "C" to cancel brewing, don't ever work for me, and it's quite annoying to quit the brewing menu. Speaking of that, the UIs would probably need some love too. For instance, every dialogue/menu should provide a way to close it easily, and no two menus should be shown together at the same time. This kind of UX polish is the polish that will elevate a good game to greatness.
Anyway, with all that said, this is still quite a nice game! Good job!
