Solid game! Reminded me of that game where you have to find the pattern that someone chose and hid. Forgot the name. But this is quite creative! The art is nice, even though it is used from a website, and the game lasts a long time.
The only thing I would do to improve is polish and enjoyment. Although the game was fun for a while, I lost interest past the first 5ish brews. What you could do is have variation everywhere. So the potions ingredients may get randomized, or an event happens, or even a day night cycle like stardew valley.
Amazing game for the time you had, 8/10
