I made a similar mixing game awhile back and for the time to take in short span this was overall pretty good.
I wish there was more UI telling me recipes to how to make things I struggled or atleast an undo button but once it was made I was forced to serve so no room for trial and error.
I know sound didnt make it but I feel adding 30 min to harmonious bg music or coffee shop music would help this go along way. Cute hand drawn style though.
