This is an adorable game! One of those games where you boot it up really not expecting much as I was very pleasantly surprised!!
Fantastic idea, and the execution was good aswell, really smooth controls and the art style, although it was minimalistic, it worked for the game as gave it a very optimistic feel.
It was also very very very challenging (in a good way), I think however, if you were to develop this further, you could add people that you want to avoid giving doughnuts to (and maybe also the addition of a wave system to give the player a bit of rest time)
But overall a really really good game that I did have a laugh to!
