This is a test to purify your skills in muscle memory as well as reflexes. This is often practiced in competitive first person shooter games as a trainer for twitch aiming. Flick your mouse to the targets and do your best to click them. Try to be fast AND accurate or else your score will suffer.
Inspired by a training aim map in a videogame. Post your score in the comments! Fullscreen is recommended, and it shouldn't slow it down any more. I would be surprised if anyone beat the record time.
