Limitation-wise I felt that it's not obvious to the kid what to do in Scratch to manage complexity - what to do when the program becomes "too big".

And just pointing out the problem and asking what could be done helped get them on track to think about the issue and ... find several ways that Scratch does allow. Splitting a program into multiple objects / agents for example.

Scratch is way more powerful than first glance or first programs hint at.
