I love how well you have utilized the theme evil COUNT bringing organization DOWN, 3,2,1 (another countdown before game begins) and not only the timer counting down, but it also impacts the gameplay too, since ones digit is the ones we get to use. The fact that we only get timer one's digit to use, meaning only way to get more number is to allow timer to go down making it more challenging and also balances risk and reward pretty well, and after using, it gets removed so wait for it to comeback thus spending time more.
Such a brilliant take on theme, very creative.
