Fantastic - I am going to see how my daughter goes with this (8 years old) - previously has been python which was great - but she could do this on her own.
It is really fantastic - the subtleties of dealing precisely with a computer (syntax) are often hard to get across, but I like how this eases them into it - but doesn't hide it away with visual programming. One of the greatest pieces of advice I was given before I started programming was that a computer will not tolerate mistakes, fuzzyness, vagueness. It will do your bidding, but no more.
