- very enjoyable game mechanic
- a bit difficult to get into: I only realized the temperature requirement after ruining the first potion
- having to juggle ingredient requesting/sorting and keeping temperature up was a bit stressful, but that's probably intended
- maybe remove the front from the ingredient box or design it in another way (perhaps a transparent jar), it hid some small ingredients almost completely
