This was fun! I liked the idea and the mechanics for it - adding the physics leads to some funny "ah crap" moments. I like the subtle background track, the sound design fits the aesthetics really well, maybe some light instruments that fade in and out with some melodies could help fill it out?
The amount of concentration to jump at the right time, on the right bat over the right cauldron was fun! I liked how easy and introductory it starts off but as you get more customers it starts to ramp up and you basic movement become crucial.
If I could suggest something, making strikethroughs on the order cards might help visually make quick decisions based on which cards need what ingredients. I saw they stay at the bottom of the cauldrons (love the spit out it does when a wrong ingredient falls in lol) but it wasn't as easy to read. Same for the font - it's beautiful, but a little hard to read at a glance (could just be me).
Overall this was a fun game with a very unique mechanic and goal - I had a lot of fun!
