Snickety is a term used to describe someone who’s picky or fastidious over detail, but not a complete snob.
There are no other practical, commonly used terms or definitions widely associated with it. Often solely found in games with a word matchup character naming system. (Those, being games for younger audiences.) So it could be said that this is meant to be a lessened version of the word persnickety.
The complaints received were snicketyat best, many just wanting small adjustments and fixes.
