Just click the donut. Try to beat the current high score. Press the space bar to reset your progress, this will also set the Donuts variable back to one.
Thank you to @GreenYoshiMario for letting me remix your game. I really appreciate it. A couple of things I've changed: I changed the baguette to a donut and I added a high score variable. I know this may not seem like much, but this is a very simple game, there's not much to change in it and @GreenYoshiMario said I could change as much as I want, no specific amount.
