When the circle is green, you are safe to click. This game is meant to be a game of will power. You can't use auto clickers because the time that the circle is red is random. If you wait too long to press the button while it's green or you press the button while it's on red, you get a strike. Three strikes and you're out. If you want to finish early because you can't keep going, press the finish button (you don't have to worry about whether it's red or green when you press finish).
I came up with this project with my friend ROOBIKCOOBS https://scratch.mit.edu/users/ROOBIKCOOBS/
