You run a donut factory! Bake donuts to serve to birds to earn money to build machines to bake more donuts. If you see icons appear on the grid, click them to gain them. Otherwise they will disappear. Click on the birds to serve them. If you don't serve them fast enough they will peck at you and you will loose hearts, and if you lose all of your hearts you'll be fired, and loose. Certain combinations of machines in the correct configuration will create new and better machines. I will now address the spelling of donut. 'Donut' is the Americanized spelling, a shortened version of the longer word, 'doughnut'. In my opinion they are both correct, and I used the shorter version simply because it's shorter. In one of my old projects, "Doughnut Dash!", I used the longer spelling. The word 'dash' is short so there was plenty of room in the title for the longer spelling of the word doughnut. For this project, I didn't want to use two long words in the title.
