What you need to do first is search for these sparkly shiny things at the end of any level known as a "Looker". Once you pick it up, you must rewind time ALL the way to the very beginning of the level. At the top-right corner of the screen you can see an icon with a timer next to it. a square face with two eyes, under the Glorb and Shard icons.
Now, from this point on, in the current level, make sure you speed run to the exact same spot where you found the "Looker" before that timer runs out (before you see a minus symbol in front of the timer). You are allowed to rewind and use time-out as much as you want to improve your speed running time (as long as you still have time-outs left). Once you managed to get to the "Looker" as fast as possible, the achievement pops.
This can be done on any level, so pick the one you feel you can speed through comfortably. I did it on the 673 chapter, where you fly around with the jetpack shooting down angel soldiers and cupids.
