To start hit the space bar. Try to avoid the balls by moving your mouse around them. If you avoid them for 30 seconds you win! If you fail and you want to try again just hit the space bar. If you win and and you want to go again you have to hit stop before hitting the space bar for some reason.
If you find any glitches report them to me in the comments so that I can fix them. Thanks!!! CHANGES: 7/20/2018; made it much easier by removing a few balls and making the remaining a bit slower
