I liked that there were no skulls or zombies, and the game was a fresh take on how to have fun.
I would have liked to have seen some sort of ingredients, other than trading muffins.
Flour, water, oil, sugar, and eggs would be main ones bakers would need, plus some trace ones like salt and baking powder, then various flavor ingredients like chocolate, berries, etc.
I'd also have liked to have seen a way to "profit" from trading, to work your way up.
The lead in suggested both a recipe (which I guess was referring to the muffin combo) as well as working your way up via trading. I think both of those could be worked on to add replay value to the game, or even a version 2.
