What a pleasing artistic direction for this game! The gameplay reminds me a lot of Overcooked, and I like the tycoon mechanic and the physics of this game.
The game gets a lot more interesting when you get a second cauldron, but it makes you wait around when you only have one. Maybe think of a nice game mechanic to add a layer to the gameplay while waiting? (Clients could be rummaging through the shop and making a mess and you have to stop them, could be a nice gameplay mechanic).
Congrats on submitting to the jam!
