had an idea for something like this a while ago
basically notes come down at random and you move your mouse in the direction of the arrows once they come down in between the white bars at the bottom, and you click on circles (not literally
on the circle, you can click anywhere within the window to get a circle)
if you move in the opposite way of an arrow it kicks you in the balls

basic and stupid but it's only a proof of concept
graphics are lazyass developer graphics
