This is such a fun and clever theme for the deck-builder genre. The whispering as you stack the ingredients is perfection. I also enjoyed how the music changed speed depending on the game state.
The only thing I would add would be the name of the ingredient on the main screen when you are choosing to keep/discard. When I first started playing I was staring at a patty and had no idea what I was looking at because of the simplified art style.
