Great presentation! All of the potion making actions I felt were very well handled, I enjoyed ringing the bell and knocking and using the pestle.
The game I thought was a little easy, I got a perfect run first try. I think maybe having ingredients that were more similar to trip the player up (like an eye of dog next to an eye of newt, or a bat's wing next to a bat's tail) for not being careful enough, or maybe a time limit on how long you have to memorize the book would have gone a ways towards the challenge.
It's also kind of a shame that winning or losing doesn't really make any difference it feels. The levels go on as normal and the ending looks functionally the same. I think it would have been cool if losing your body parts had a gameplay consequence, like maybe missing a bone makes your hand wobble so it's harder to grab things or something along those lines.
Overall though I think you cultivated a great atmosphere and the mechanisms were all very well implemented, nice work!
