Very good, one little problem – LetterSchool - Block Letters Review

This is a great app. Very well designed and fun. My preschooler likes playing and learning with it. My only complaint is that the tolerance for tracing the letters is a bit too tight for my little guy. He traces a letter most of the way but then his finger inevitably wanders off the line just a tiny bit (but he's still basically on target) and the app makes him start over. This frustrates him and he ends up asking me to do it for him. Is there a way to set how "strict" the tracing is? Otherwise, excellent app, highly recommend.
