Sometimes dark humour is great. Mmmm, meeple. The contrast in music between watching a grinding is a nice humourous touch. Also, I saw that you changed your game itch tag to "potato". I see what you did, heh.
As far as using proof-of-concepts instead of more fleshed out demos, they are very good at pointing out mechanics that need some work very early on before too much development work went into those mechanics. This one evidences that: it is tedious to grab the cup and grab the meeple juice, then drag that over to a house. I would have cut out the cup entirely, just dragging the mortar and pestle over itself to the houses. Also, you want to avoid forcing a player to move their mouse across the entire screen in quick sucession- maybe just 1. making the pestle bigger, and 2, moving it to the right of the screen underneath the controls would be substantial.
