Overview
A video guide on how to get the Deft Touch achievement.
Achievement video guide
(Video made by me). Please bear in mind that while I didnt unlock the achievement in the video, I have already unlocked it (check my stats). I unlocked it using this exact method. You ARE allowed to erase lines and it will unlock (at least, it did for me). Please bear in mind NOT to scribble while waiting for the doodles, as that will mean no achievement for you (I got bored).
