I really like the art style and the idea of mixing potions together seems pretty neat, but I didn't really understand how the game works. I think having the tutorial talk about where the potions should be moved and what to do after you add the powders to the flasks would help. I also didn't know tab closed the potion ingredients screen until I started pressing buttons at random.
I saw that you had some problems with the build towards the end, so maybe these things were fixed in there. I'd say you should upload that version as well, maybe titled v1.1 or something, so we could play the more finished version
Also, I'm not really sure how the game ties in with the theme of the jam?
